AB  - Magnetic iron oxide nanomaterials, which enable a multitude of uses, are given special focus in the fields of biomedicine and environmental protection. The detection, sorption, and/or degradation of inorganic (lead, chromium, arsenic, and cadmium), organic (dyes, pharmaceuticals, pesticides, phenols, and benzene), and biological (viruses and bacteria) pollutants can all be effectively accomplished with the use of magnetic nanoparticles. Magnetic iron oxide nanomaterials are in particular focus for use as hyperthermia media in cancer treatment and as magnetic resonance imaging (MRI) contrast agents. The possibility of magnetic separation of such materials, due to their essential properties under the influence of an external magnetic field, reduces production costs and also prevents the production and accumulation of toxic waste. Among the many metal oxide nanomaterials, magnetite (Fe3O4) and maghemite (γ-Fe2O3) are currently the only two magnetic materials approved by the US Food and Drug Administration (FDA) for human use as iron deficiency therapeutics and as contrast agents for MRI. Here, we synthesized nanoparticles of magnetite (Fe3O4) by the method of reduction-precipitation and characterized. Additionally, potential binding of brilliant green dye on Fe3O4 and construction of innovative magnetic composite was investigated. The physicochemical features were explored using X-ray diffraction (XRD), 
Fourier-transform infrared spectroscopy (FTIR), and field emission scanning electron microscopy (FESEM). XRD analysis confirms formation of the crystal phase of magnetite. The presence of magnetite nanoparticles is shown by typical groups for the peaks of iron compounds at a lower wavelength (≤ 700 cm-1) that are characteristic of the Fe-O bond. Morphological analyzes with FESEM showed that magnetite is a composite of nanospheres and nanorods that provide a large surface area. Dye binding study was performed using UV visible and FTIR spectrometer.

AB  - Acid mine drainage is a challenging environmental problem caused by mining activities. Long-term  copper  ore  exploitation  and  vast  amounts  of  mining  waste  lead  to  severe  soil  contamination as well as river and groundwater pollution. In this paper, research is focused on utilizing waste mine waters and off-balance parts of the mine deposit (such as flotation tailings) and converting their negative characteristics to an environmentally friendly one. In the  authors’  previous  work,  acid  mine  water  from  Robule,  which  is  part  of  the  Bor  copper  mining and smelting complex in Serbia, was successfully treated using flotation tailings, and the resulting solution was suitable for safe discharge. This paper investigates the characteristics of the solid residue that remained after the treatment of the modified flotation tailings in order to  evaluate  the  possibility  of  its  safe  disposal  back  into  the  environment.  The  solid  residue  was subjected to TCLP and EN 12457-4 tests as standard procedures that assess the leaching characteristics  of  a  material.  The  solid  residue  was  also  exposed  to  long-term  leaching  with  melted  snow  to  simulate  environmental  conditions  for  one  year.  This  drainage  water  was  analyzed and compared with the results of the standard leaching procedures. The investigated treatments lead to improved economic and environmental effects, while the process itself is adjusted to preserve the environment.

AB  - Following the principles of sustainable development and circular economy, an innovative industrial symbiosis approach
has been developed that uses already disposed voluminous waste. The research was focused on the utilization potential
of vast amounts of flotation tailings, fly ash and acidic mine waters. Numerous previous case studies have pointed out the
harmful, long-lasting environmental damage from waste disposal. In this case, the emphasis is on finding a practical
approach for using industrial waste, specifically thermal power plant fly ash, in order to neutralize acidic mine waters
resulting from tailings disposal. The proposed treatment gives waste a practical value, eliminates its harmful effect on the
environment and redefines (lowers) regular waste management costs. In addition, it is possible to obtain valuable metals
by exploiting and reprocessing acidic mine drainage.

AB  - Two medium-carbon microalloyed steels with a predominant acicular ferrite microstructure were investigated in this study in order to determine the initial micro-crack formation mechanism and the role of acicular ferrite structure in cleavage fracture. In order to ensure cleavage fracture, samples were investigated at −196 ◦C for uniaxial tension and four point bending fracture. Previous investigations have shown that cleavage fracture for steels with a predominant acicular ferrite microstructure has not been initiated by the fracture of coarse TiN particles as in ferrite-pearlite,
bainite, or martensitic microalloyed steels. The average maximal thickness of cementite plates measured in this work is 0.798 µm and 0.966 µm, for V and TiV steel, respectively. The corresponding stress values required for their fracture according to Griffith’s equation are 1970 MPa and 1791 MPa,
respectively. Estimated values of the effective surface energy for the V steel with an average cementite volume fraction of 3.8% range from 40 Jm−2 to 86 Jm−2, and for the TiV steel with an average cementite volume fraction of 18.3% range from 55 Jm−2 to 82 Jm−2. The fracture of coarse cementite plates was found to not to be responsible for the cleavage fracture initiation in case of both steels.

AB  - Phytomining although predominantly in its early stages on the broader scientific scope of investigation has garnered
interest in metals such as Ni, Au, Zn or REE. Rare earth elements (REE) are commonly defined as the 15 lanthanides
with the addition of Sc and Y. Since studies of other hyperaccumulating plant species have been conducted before, similar techniques were tried with REE. With the concentration threshold at 0.1 wt% of the dry biomass there have been identified about 22 plant species that hyperaccumulate REE from five families (Phytolaccaceae. Gleicheniaceae, Blechnaceae, Juglandaceae, Thelypteridaceae). One of the most studied REE hyperaccumulators is Dicranopteris linearis (formerly
known as D.dichotoma), a fern native to China that grows on mine tailings. Generally, the techniques for REE
phytomining can be separated into Pyrometallurgy, Hydrometallurgy, Biometallurgy and Novel approaches. Currently most of the research is still focusing on the optimal utilization of various hiperaccumulators and the enchantment of REE extraction from the soil as well as from the enriched biomass. Since recovery of REEs via phytomining is just in its
infancy further multidisciplinary investigations are needed, especially when it comes to valorization and REE recovery.
This paper presents a quick review for the concept of REE phytomining, current state of research, challenges and
prospects.

AB  - In oxygen converters, molten iron from the blast furnace is refined with steel waste under oxidizing conditions [1]. The injected oxygen passes into the iron melt, after which it reacts with the impurities. Analysis of exergy losses clearly indicates the place of energy losses in the observed process, so a detailed analysis can influence the improvement of a complex process [2]. Exergy losses occur due to technological imperfections such as heat dissipation or friction and system irreversibility according to the second law of thermodynamics [3]. The concept of exergy can be used for a better understanding of the feasibility of a process, as well as for the techno-economic analysis of the process at different variations of input/operating parameters. In this work througtful calculation of exergy oxygen convertor was done. According to the obtained data, out of a total of 972.2 MJ of thermal energy, which is released by exothermic reactions in the refining process, 817.5 MJ is pure exergy and can be used, the rest is anergy that arises due to irreversibility.

AB  - Aluminothermic welding has been used to connect railway rails for over a century. This technique has the advantages of flexibility, weld compactness, and simplicity. External energy is not required for the procedure. Exothermic heat is produced by chemical reactions of aluminothermic elements. To create a quality welded connection, the mold and pouring system must provide uniform pouring of hot steel
without turbulence, even heat dissipation or cooling, and an acceptable micro and macro structure of steel free of internal and external faults. The design of the mould was constantly changing, necessitating costly industrial experimentation. As a result, the mould's design was constantly evolving, necessitating the use of costly experimental procedures in industrial settings. The latest iteration of the model the
casting cavity was improved by adding hoes in the sand and putting rails on both sides in order to more aquratly simuate heat transfer. Software programs are emulating conventional casting procedures for thermite steel casting in welded railway connections to save money and effort on costly and timeconsuming industrial testing. For the 49E1 rail, NovaFlow & Solid CV were utilized to simulate casting thermite steel in the mould cavity or weld junction.

AB  - The paper presents the results of the analysis of the influence of the synthesis parameters on obtaining the composite
system (WAl12 + Al2O3)/Al with improved mechanical properties. The starting powders of Al and WO3 were
homogenized until reaching the required composition with 1%, 2%, 5% and 7% WO3. After homogenization,
the obtained samples were pressed under a pressure of 10 MPa. The sintering of the obtained samples was performed
in an argon atmosphere at temperatures of 550 oC, 585 oC, 615 oC and 650 oC for 20, 40 and 60 minutes. As a result
of the test, it was concluded that the sintering temperature, as well as the sintering time, do not have a significant effect
on the increase in hardness of these composites. The main parameter that affects the increase in strength of these
composites is the WO3 content. With an increase in the WO3 content, there is an increase in the hardness of
the composite.

AB  - Naučnici su otkrili plastiku ranih 1900-ih, ali nisu shvatili kakve štetne efekte njena fragmentacija može imati na životnu sredinu 100 godina kasnije. Konkretno, čestice nanoplastike (NP) veličine od 1 do 100 nm mogu izazvati velike probleme u živom svetu zbog svoje velike specifične površine za adsorpciju drugih zagađujućih materija iz vode i njihove dalje bioakumulacije kroz lanac ishrane.

Iako mnoge metode razvijene za proučavanje mikroplastike nisu direktno primenljive na nanoplastiku, konvencionalne metode karakterizacije nanoplastike su obično zamorne jer proučavaju pojedinačne nanočestice u izolaciji. Pošto nanoplastika koja je rezultat razgradnje mikroplastike ima drugačija svojstva od sintetisanih plastičnih nanočestica, potrebno je razviti nove tehnike koje će nam pomoći da bolje razumemo ozbiljnost problema nanoplastike.

AB  - Scientists discovered plastic in the early 1900s, but didn't realize the detrimental effects its fragmentation could have on the environment 100 years later. In particular, nanoplastics (NPs) particles ranging in size from 1 to 100 nm can cause major problems in the living world due to their high specific surface area for the adsorption other polluting substances from water, and their further bioaccumulation through the food chain. There is no distinctive method to identify, characterize, and quantify nanoplastics in aquatic environments. Although many of the methods developed to study microplastics are not directly applicable to nanoplastics, conventional methods of characterizing nanoplastics are usually tedious because they study individual nanoparticles in isolation. Since nanoplastics resulting from the decomposition of microplastics have different properties than engineering plastic nanoparticles, new techniques need to be developed to help us better understand the seriousness of the nanoplastic problem. Nanoplastic can be isolated from the water environment by a combination of filters and ultracentrifugation. A recent publications states that combining microscopy and spectroscopy, supported by chemometric techniques, will alow a better understand he behavior of nanoplastic particles in the environment and organisms. High hopes are placed on microscopies combined with neural networks for the quantification and characterization of nanoplastics in complex systems. This article describes the degradation pathways of plastics and the formation of nanoplastics in aquatic environments, and possible methods for separation and characterization of nanoplastics in relation to recent publications.

AB  - Railway rails have been linked using the aluminothermic welding process for over a century. This method has several
advantages, including flexibility, compactness of the weld, and ease of execution. It is not necessary to employ outside
energy to complete the procedure. It is provided by the exothermic effect of the chemical reactions of the aluminothermic combination's elements. The design of the mold with the pouring system, which should ensure even pouring of thermal steel without turbulence, then even heat dissipation or cooling in order to obtain an appropriate micro and macro structure of steel, free of internal and external defects, is an important factor in producing the required quality welded joint. As a result, the mold's design was constantly evolving, necessitating the use of costly experimental procedures in industrial settings. In this iteration of the model the casting cavity was improved by adding hoes in the sand and putting rails on both sides in order to more aquratly simuate heat transfer. Software programs are being used to simulate conventional
casting procedures that can be used in the casting of thermite steel during the fabrication of welded railway connections
in order to prevent costly and time-consuming industrial experimentation. The NovaFlow & Solid CV software package
was used to simulate casting thermite steel in the mold cavity, i.e. in the weld joint, for the 49E1 rail.

AB  - Aluminothermic welding has been used to connect railway rails for over a century. This method has several advantages, including its versatility, the tightness of the weld it creates, and its ease of execution. To complete the procedure, no further power source is necessary. The design of the mold with the pouring system, which should ensure even pouring of thermal steel without turbulence, then even heat dissipation or cooling to obtain an appropriat  micro and acro structure of steel free of internal and external defects, is one of several factors that contribute to a quality welded joint. As a result, costly experimental techniques in industrial settings were necessary to keep up with the ever-changing mould design. The model design was upgraded in comparison to the previous version [1], and will be imroved even further.The two sets of solid steel rails put on either side of the casting mould will be adjusted as heating media within the mould material category in the future, bringing the model closer to reality. As a result, cooling and heating temperatures will be more evenly distributed. Stress and strain modeling were performed to the preheated model to provide a more complete understanding of how shrinkage is related to stress. In future iterations of the model, we will either move the heat source to its right place approximately 40 cm above ground or adjust the temperature, diameter, and gas at the current site to more exactly reproduce real-life circumstances. Furthermore, during simulation setup, the
replace material function may be used to model a new component that represents the divider that will be changed between air and silica sand material at the end of
prehearing. Software programs are being used to simulate conventional casting procedures that may be used in the casting of thermite steel during the fabrication
of welded railway connections in order to prevent costly and time-consuming
industrial experimentation. The NovaFlow & Solid CV software suite [2] was used
to simulate casting thermite steel in the mold cavity or weld joint for the 49E1 rail.

AB  - Numerous electronic devices are put out of use every day, and most of them have printed circuit boards (PCBs) that are lased and imbued with various precious and valuable metals in abundant amounts. This makes PCB an unexploited resource of the future from whom many metals such as Cu, Zn, Sn, Al, Li, Co, Nd, Pd, Pt, and Ba can be extracted. Since leaching plastic polymers can lead to the vaporization of toxic fumes, to avoid this the PCB are pyrolyzed. The PCB is crushed and the pyrolyzed product is a powder that can easily be separated into metallic and nonmetalic fractions. The aim of this work is to investigate the influence of ultrasound sonification on the nitric acid leaching of pyrolyzed printed circuit board (PPCB) powder. The impact of ultrasound sonification had a positive effect on the leaching degree for all investigated metals except for Cobalt. The biggest difference in leaching degree was for Lithium while the smallest was for platinum. Because of the complexity of the PPCB powder system overall, the measurement of oxidation-reduction potential (ORP) didn’t yield any insight into the leaching mechanism since the measured values mainly followed the expected trend due to nitric acid degradation.

AB  - Recent mankind demand for electronic devices is in constant upgrowth, those devices
always contain printed circuit boards (PCB) which are mainly constructed of plastics, semiconductors
and decent content of various metals. Hence, in the end-of-life of those
products, it is highly recommended to recover those materials or functionalize those waste
into other products or feed materials, in order to lessen their harmful impact on the
environment. One of the promising processing procedures is hydrometallurgical treatment,
since it is cost-effective and simple. In order to recover metals as aqueous soluble salts,
crushed and milled PCB is air-pyrolyzed and obtained powder is processed as start material
in leaching experiments. The use of concentrated aqua regia led to the passivation of solid
material and consequently impede the leaching process. Dry-digestion leaching using
concentrated sulfuric acid partially leached some metals. The highest leaching rate (≥70 %)
has been achieved using diluted sulfuric acid (for Al, Ni, Fe, Co, and rare-earth) and copper
yield was highest utilizing 2 M H2SO4 + 3 M H2O2; S/L = 0.1 g/ml. While sulfuric acid has
accomplished some results for enumerated leachates, it achieved limited success for
leaching Ba, Pb, Ag, Au, Pt and Pd. Overall findings imply that hydrometallurgical
procedures may be used but only together with previous separation techniques. That
approach would increase overall leaching with oxidizing agents and enable leaching of
noble metals.

AB  - For more than a century, railway rails have been joined using the aluminothermic welding process. The flexibility, compactness of the weld, and ease of execution are all advantages of this process. It is not necessary to use external energy to finish the operation. It is provided by the exothermic effect of the chemical reactions of the elements of the aluminothermic combination. The design of the mold
with the pouring system, which should ensure even pouring of thermal steel, without turbulence, then even heat dissipation or cooling in order to obtain an appropriate micro and macro structure of steel, free of internal and external defects, is an important factor in producing a welded joint of the required quality. As a result, the design of the mold was continually developing, necessitating the adoption of expensive experimental approaches in industrial settings. To eliminate costly and time-consuming industrial experiments, software applications are being employed to imitate aditional casting methods that can be used in the casting of thermite steel during the fabrication of welded railway connections. This study presents a simulation of casting thermite steel in the mold cavity, i.e., in the weld joint, for the 49E1 rail using the NovaFlow & Solid CV software package.

there are free of charge alkaline wastes, suitable to
neutralize the AMD by altering pH, which leads to
precipitation of valuable metal which can be reused,

composition of the initial samples of FJM and FA
was evaluated two standard leaching tests: TCLP

Capacity test. These base materials were shown to
have a large capacity to neutralize acid, making
them a highly effective alternative material for
neutralizing acid mine drainage and eliminating
metals, even better than results of neutralisation
with NaOH, as conventional reagent. According to
the findings the FJM and FA neutralization
experiments precipitated more than 99 % of Al, Fe,
and Cu, 90 % of Pb, and 92 % of Zn. Leaching of
these metals from FJM and FA raises Cd and Mn
concentrations. Additional treatment was
undertaken using hydrated lime to boost the pH to
10 and so offer circumstances for its removal, in
order to reduce the concentration of Mn below the
authorized limits by Serbian legislation. At the end,
as a result of utilizing alternative materials such as
FJM and two FA purified water, safe for release into
the environment was obtained. In this way,
resources are preserved for the future generation,
and the treatment of already disposed amounts of
waste reduces the contamination of the

AB  - Electric waste from numerous devices that are put out of use every day has some form of printed circuit board that contains precious and valuable metals in their components. In order to extract these metals, the printed circuit boards were crushed and pyrolyzed into powder. The fine pyrolyzed printed circuit board (PPCB) powder was separated into fractions, and the fine metallic fraction was used as a raw material for metal leaching extraction. In order to better understand how various metal species react in leaching media, several leaching agents were used (sulfuric acid, nitric acid, glycine, and acid mine drainage-AMD) alone, and with the addition of hydrogen peroxide. Additionally, the influence of the S/L ratio and leaching temperature were investigated in sulfuric acid leaching solutions, as this is the one most widely used. In one case, the reactor was heated in a thermal bath, while in the other, it was heated in an ultrasonic bath. Lastly, several experiments were conducted with a (consecutive) two-pronged leaching approach, with and without applied pretreatment. The aim of this paper is to give a multifocal and detailed approach to how metals such as Al, Cu, Co, Zn, Sn, and Ca behave when extracted from fine PPCB powder. However, some attention is given to Nd, Pd, Pb, and Ba as well. One of the main findings is that regardless of the pretreatment or the sequence of leaching media applied, consecutive two-pronged leaching cannot be used for selective metal extraction. However, AMD was found to be suitable for selective leaching with very limited applications.

abstract = "Electric waste from numerous devices that are put out of use every day has some form of printed circuit board that contains precious and valuable metals in their components. In order to extract these metals, the printed circuit boards were crushed and pyrolyzed into powder. The fine pyrolyzed printed circuit board (PPCB) powder was separated into fractions, and the fine metallic fraction was used as a raw material for metal leaching extraction. In order to better understand how various metal species react in leaching media, several leaching agents were used (sulfuric acid, nitric acid, glycine, and acid mine drainage-AMD) alone, and with the addition of hydrogen peroxide. Additionally, the influence of the S/L ratio and leaching temperature were investigated in sulfuric acid leaching solutions, as this is the one most widely used. In one case, the reactor was heated in a thermal bath, while in the other, it was heated in an ultrasonic bath. Lastly, several experiments were conducted with a (consecutive) two-pronged leaching approach, with and without applied pretreatment. The aim of this paper is to give a multifocal and detailed approach to how metals such as Al, Cu, Co, Zn, Sn, and Ca behave when extracted from fine PPCB powder. However, some attention is given to Nd, Pd, Pb, and Ba as well. One of the main findings is that regardless of the pretreatment or the sequence of leaching media applied, consecutive two-pronged leaching cannot be used for selective metal extraction. However, AMD was found to be suitable for selective leaching with very limited applications.",

AB  - The aim of this work was to establish a temperature of finish rolling stage of Nb/Ti microalloyed steel containing 0.06 wt.% C, 0.77 wt.% Mn, 0.039 wt.% Nb and 0.015 wt.% Ti, using physical simulation. Samples were subjected to laboratory simulation at a twist plastometer at high temperatures, i.e. between 825 and 950 degrees C. Five pass deformation and interpass times were selected in accordance with a processing parameters at five stand finishing hot strip mill. Restoration (recovery and/or recrystallization) behavior was evaluated by calculation of Fraction Softening (FS) and Area Softening Parameter (ASP) values. At 950 degrees C all individual pass stress-strain curves, FS and ASP show full recrystallization in all interpass intervals. On the other hand, with a decrease in temperature to the interval of 875-825 degrees C, the extent of restoration is decreasing, leading to recovery as a sole softening mechanism at 825 degrees C, which was confirmed by the stress-strain curve shape, and values of FS and ASP. It is assumed that, due to high supersaturation, strain-induced precipitation promoted pinning of grain and subgrain boundaries and suppressed recrystallization. Therefore, the critical temperature for finish rolling was estimated to be 825 degrees C.

AB  - Cleavage fracture of the V and Ti-V microalloyed forging steels was investigated by the four-point bending testing of the notched specimens of Griffith-Owen's type at -196 degrees C, in conjunction with the finite element analysis and the fractographic examination by scanning electron microscopy. To assess the mixed microstructure consisting mostly of the acicular ferrite, alongside proeutectoid ferrite grains and pearlite, the samples were held at 1250 degrees C for 30 min and subsequently cooled instill air. Cleavage fracture was initiated in the matrix under the high plastic strains near the notch root of the four-point bending specimens without the participation of the second phase particles in the process. Estimated values of the effective surface energy for the V and the Ti-V microalloyed steel of 37 Jm(-2) and 74 Jm(-2), respectively, and the related increase of local critical fracture stress were attributed to the increased content of the acicular ferrite. It was concluded that the observed increase of the local stress for cleavage crack propagation through the matrix was due to the increased number of the high angle boundaries, but also that the acicular ferrite affects the cleavage fracture mechanism by its characteristic stress-strain response with relatively low yield strength and considerable ductility at -196 degrees C.

AB  - Phytomining, although predominantly in its early stages on the broader scientific scope of investigation, has garnered interest in metals such as Ni, Au, or rare earth elements (REE). However, Zn pollution from mine wastes, smelters, coal ash and other anthropogenic sources has become an environmental problem. Phytoremediation by hyperaccumulating plants is one of the proposed solutions to mitigate the pollution. Therefore, a need to utilize or dispose Zn hyperaccumulating plants occurred. Since studies of certain hyperaccumulating plant species have been previously conducted in order to extract metal products, similar hydrometallurgical and pyrometallurgical techniques were tried with Zn. The hydrometallurgical route was more focused on producing crude eco catalysts for organic chemistry or separating metal hydroxides by cementation. This was achieved with acid leaching of the ash which was obtained by calcinating the aboveground plant biomass. On the other hand, the pyrometallurgical route was more focused on safe and eco-friendly disposal of combustion products such as ash or biochar, while achieving zero toxic gaseous emissions from biomass pyrolysis. Regardless of the approach further research is needed to investigate the stabilization of metals that remain in the solid fraction during combustion and lowering the metal content in produced gases. So far, none of these technologies have been brought to a semi industrial scale and there is the potential of linking those two approaches together.

AB  - Acid mine drainage (AMD) is a waste from mining sites, usually acidic, with high concentrations of sulfates and heavy metal ions. This study investigates the AMD neutralization process using fly ash (FA) as an alternative material. Samples of FA from coal-fired power plants in Serbia ("Nikola Tesla" (EF) and "Kostolac" (KOST)) were analyzed and used. The results were compared with the treatment efficiency of commercial neutralization agent (NaOH). The alkaline nature of FA was the basis for use in the treatment process of the extremely acid Lake Robule (pH 2.46), located in the mining areas of eastern Serbia. The optimal S/L ratio for the AMD neutralization process determined for EF was 25 wt.%, and for KOST it was 20 wt.%. The mechanism of the neutralization process was analyzed using the ANC test and PHREEQC program. The element concentrations and pH values in solutions indicated that FA samples could neutralize Lake Robule with more than 99% of Al, Fe, Cu, Zn, and more than 89% of Pb precipitated. Formation of insoluble (oxy)hydroxide forms (Fe3+ and Al3+ ions) creates favorable conditions for co-precipitation of other trace metals (Cu, Zn, Ni, Pb, and Cd) from AMD, which is further enhanced by cation adsorption on FA particles. FA proved to be a more effective neutralization agent than NaOH due to its adsorption effect, while among the FA samples, KOST was more effective due to the aging process through the carbonization reaction. Using FA as an alternative material is a promising and sustainable method for treating AMD, with economic and environmental benefits.

AB  - Fitorudarenje je aktuelna biotehnologija u razvoju kojom se ekstrahuju retki i dragoceni metali iz prirodno obogaćenih ili zagađenih zemljišta uz pomoć biljaka hiperakumulatora. Na teritoriji Balkana hiperakumulatorske vrste usvajaju prevashodno nikl, cink, talijum, bakar i arsen. U ovom radu dat je pregled do sada ispitanih tehnologija za ekstrakciju ovih elemenata iz biomase hiperakumulatorskih vrsta širom sveta, kao i područja potencijalne primene dobijenih produkata. Na teritoriji Srbije fitorudarenje ima perspektivu, i potrebno je vršiti ispitivanja u pravcu pronalaženja upotrebne vrednosti dostupnih hiperakumulatora, kao i razvoja tehnologija za ekstrakciju metala iz njihove biomase.
AB  - Phytomining is a currently developing biotechnology aiming to extract rare and precious metals from naturally enriched or polluted soils with the help of hyperaccumulator plants. On the territory of the Balkans, hyperaccumulating species mainly accumulate elements such as nickel, zinc, thallium, copper and arsenic. This paper provides an overview of the studied technologies around the world for the extraction of these elements from hyperaccumulator's biomass, as well as the areas of potential application of the obtained products. Phytomining has a potential for development in Serbia, and for this purpose it is necessary to utilitized available hyperaccumulators, as well as to investigate technologies for the extraction of metals from their biomass.

Na teritoriji Balkana hiperakumulatorske vrste usvajaju prevashodno nikl, cink, talijum, bakar i arsen. U ovom radu dat je pregled do sada ispitanih tehnologija za ekstrakciju ovih elemenata iz biomase hiperakumulatorskih vrsta širom sveta, kao i područja potencijalne primene dobijenih produkata. Na teritoriji Srbije fitorudarenje ima perspektivu, i potrebno je vršiti ispitivanja u pravcu pronalaženja upotrebne vrednosti dostupnih hiperakumulatora, kao i razvoja tehnologija za ekstrakciju metala iz njihove biomase., Phytomining is a currently developing biotechnology aiming to extract rare and precious metals from naturally enriched or polluted soils with the help of hyperaccumulator plants. On the territory of the Balkans, hyperaccumulating species mainly accumulate elements such as nickel, zinc, thallium, copper and arsenic. This paper provides an overview of the studied technologies around the world for the extraction of these elements from hyperaccumulator's biomass, as well as the areas of potential application of the obtained products. Phytomining has a potential for development in Serbia, and for this purpose it is necessary to utilitized available hyperaccumulators, as well as to investigate technologies for the extraction of metals from their biomass.",

AB  - Coal is a well-known fossil fuel. It was used as a non-renewable energy source for several centuries. Nowadays it is mainly used for electricity generation in power plants or heat generation for industrial and home utilization.
There are many types of coal that differ in composition and calorific value, as well as in the amounts of undesired hazard substances produced by combustion. Depending on the coal composition, environmental impact can be reduced by its treatment before combustion. One of the cheap and effective methods is the chemical leaching of coal that reduces sulfur content and the amount of mineral matter (ash). Lowering the ash amount increases the calorific value of coal, reduces its transportation cost, and reduces the negative environmental impact of toxic elements, which are usually present in ash. Another benefit of coal leaching, that results from lowering the sulfur content is reduced emission of toxic gases (SO2 and SO3) during combustion. In order to determine the optimal leaching conditions for the treatment of different types of coal, numerous studies have been done, investigating various chemical reagents, including inorganic and organic acids, alkalis, oxidative reagents, and their combinations [1, 2]. The key parameters that effect leaching efficiency are type and concentration of reagent, reaction temperature, the mass ratio between coal and leaching reagent, coal particle size, and reaction time. The degree of leaching efficiency is measured by the level of demineralization and desulphurization [3]. The current review summarises recent results and further plans for the development of an efficient and environmentally friendly method for the chemical leaching of Serbian sub-bituminous coal.

AB  - All over the world, huge amounts of coal are available and it is utilized in large quantities for different
purposes. The coal combustion causes environmental problems, such as the release of toxic metals
and other pollutants into wastewaters, emission of noxious gases, produce of ash dumps, etc. One of
the solutions for the reduction of environment pollution, caused by coal combustion, is
demineralization and desulphurization of coal. In that sense, treatment of coal by different chemical
reagents becomes important. A subbituminous coal, used in this study was taken from the Bogovina -
East field (Lower Miocene » 20-16 Ma) of the Bogovina Basin, which is located in Eastern Serbia. The
sample was selected based on the previous studies of Bogovina - East field which indicated a high
amount of sulphur, relatively high percent of mineral matter and considerably amount of liptinites
for humic coal, which represent the most reactive maceral group. The aim of the study was an
attempt to reduce the amount of ash and sulphur in coal, keeping the organic matter unaltered as
possible, using simple and cheap method e.g. treatment with hydrochloric acid (HCl). Ash and total
sulphur content was determined before and after HCl leaching. In addition characteristics of initial
and treated coal were tracked by X-ray diffraction (XRD) analysis and Fourier-transform infrared
(FTIR) spectroscopy. The obtained results showed that the high percentage of deashing (» 80 %) was
achieved with cheap hydrochloric acid. XRD analysis of ash before and after sample treatment
provides more information about mineral phases in coal and effects of chemical leaching. FTIR
analysis indicates almost no changes in structure of coal organic matter after treatment by HCl,
which is important for further coal usage (e.g. combustion). On the other hand, the applied chemical
leaching with HCl had low impact on the sulphur content in Bogovina coal (desulphurization
percentage » 8 %). Therefore, in future research other reagents for efficient desulphurization should
be investigated.
