AB  - Отпадне воде представљају велики еколошки притисак на читав екосистем.
Загађујуће материје у отпадној води, као што су боје, могу изазвати токсичне после-
дице по живи свет. Из тог разлога је потребно развити нове, ефикасне материјале који
у процесу адсорпције могу да уклоне присутне полутанте и реше проблем загађења.
Слојевити двоструки хидроксиди добијени процесом таложења при ниском преза-
сићењу примењени су у процесу уклањања боје метанил-жуто из водених раствора.
Приликом експеримената, варирани су параметри као што су маса адсорбента, време
контакта, температура. Добијеии резултати показују висок адсорпциони капацитет 74
mg g-1 и ендотермну природу процеса адсорпције.
AB  - Wastewater represents a major environmental pressure on the entire ecosystem.
Pollutants in wastewater, such as dyes, can cause toxic effects on living beings. Therefore, it
is necessary to develop new, efficient sorption materials that can remove the present
pollutants and solve the pollution problem. The layered double hydroxides obtained by the
co-precipitation process at low supersaturation were applied in the process of removing methanil-yellow color from aqueous solutions. During the experiments, parameters such
as adsorbent mass, contact time, and temperature were varied. The obtained results
show a high adsorption capacity of 74 mg g-1 and an endothermic nature during

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  - This paper aims to show a short economic analysis of the profitability of recycling management on the territory of Paraćin
municipality. Consumption habits of modern society and socioeconomic conditions have made it difficult to implement
sustainable waste management strategies. Industry, economics, sociocultural and political activities must work together
to solve the multifaceted problem of waste management. The municipality of Paraćin is located in the central part of the
Republic of Serbia, Pomoravlje region. Annually, this municipality generates about 18,000 t of waste, while the mass of
recyclable waste is approximately 7,000 t. This small industrial city have been constantly facing with an insufficient
number of available bins and containers for the disposal of Municipal Solid Waste (MSW). Moreover, this city has been
challenging by an increasing number of illegal dumps along the roads. Together with surrounding municipalities, the local
government was planning to create Regional Recycling Center and Landfill with all necessary operations. Sorting of the
waste at the source of its origin, and adequately disposing it in containers intended for different types of waste, would
provide precisely insight into the movement of recyclable waste. In addition, with these actions by the local community,
it could produce a habit among citizens for proper deposition and disposal of household waste and reduce the negative
impact on the environment. This article shows the categories of waste and their percentages, as well as the resulting
amount of recyclable waste, which should be a starting point for establishing a recycling center with surrounding
municipalities.

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  - 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  - 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.

This revolutionary transformation will generate a growing demand for metallic raw materials that are a crucial part of batteries-nickel and cobalt, among others. Providing enough raw materials for e-mobility in a sustainable way will be a challenge in the years to come.

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.

AB  - Iako u ranoj fazi istraživanja fitorudarenje je podstaklo interesovanje u ispitivanju metala poput Ni, Au i retkih zemalja (REE). Međutim zagađenje cinkom iz rudničkog otpada, topionica, letećeg pepela i drugih antropogenih izvora postalo je ekološki problem. Fitoremedijacija hiperakumulirajućim biljkama pokazala se kao jedno od rešenja za smanjenje tog zagađenja. Stoga se pojavila i potreba za korišćenjem ili odlaganjem biljaka-hiperakumulatora cinka. Pošto su ranije sprovedena ispitivanja određenih hiperakumulatora za ekstrakciju metala, slični hidrometalurški i pirometalurški postupci ispitani su i za Zn. Hidrometalurški pravac ispitivanja fokusiran je na proizvodnju grubih eko katalizatora za potrebe organske hemije ili separaciju metalnih hidroksida cementacijom. Ovo je postignuto kiselim luženjem pepela dobijenog sagorevanjem nadzemne biomase. S druge strane, pirometalurški pravac više je fokusiran na bezbedno i ekološki prihvatljivo odlaganje proizvoda sagorevanja poput pepela i biočađi, uz postizanje nulte emisije toksičnih gasova pri pirolizi biomase. Bez obzira na pristup, potrebna su dalja istraživanja kako bi se ispitala stabilizacija metala koji zaostaju u čvrstoj frakciji tokom sagorevanja kao i smanjenje sadržaja metala u emitovanim gasovima. Do sada nijedna od ovih tehnologija nije dovedena do poluindustrijskih razmera u ispitivanjima, mada postoji potencijal u povezivanju ova dva pristupa.
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.

abstract = "Iako u ranoj fazi istraživanja fitorudarenje je podstaklo interesovanje u ispitivanju metala poput Ni, Au i retkih zemalja (REE). Međutim zagađenje cinkom iz rudničkog otpada, topionica, letećeg pepela i drugih antropogenih izvora postalo je ekološki problem. Fitoremedijacija hiperakumulirajućim biljkama pokazala se kao jedno od rešenja za smanjenje tog zagađenja. Stoga se pojavila i potreba za korišćenjem ili odlaganjem biljaka-hiperakumulatora cinka. Pošto su ranije sprovedena ispitivanja određenih hiperakumulatora za ekstrakciju metala, slični hidrometalurški i pirometalurški postupci ispitani su i za Zn. Hidrometalurški pravac ispitivanja fokusiran je na proizvodnju grubih eko katalizatora za potrebe organske hemije ili separaciju metalnih hidroksida cementacijom. Ovo je postignuto kiselim luženjem pepela dobijenog sagorevanjem nadzemne biomase. S druge strane, pirometalurški pravac više je fokusiran na bezbedno i ekološki prihvatljivo odlaganje proizvoda sagorevanja poput pepela i biočađi, uz postizanje nulte emisije toksičnih gasova pri pirolizi biomase. Bez obzira na pristup, potrebna su dalja istraživanja kako bi se ispitala stabilizacija metala koji zaostaju u čvrstoj frakciji tokom sagorevanja kao i smanjenje sadržaja metala u emitovanim gasovima. Do sada nijedna od ovih tehnologija nije dovedena do poluindustrijskih razmera u ispitivanjima, mada postoji potencijal u povezivanju ova dva pristupa., 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  - This paper examines the effects of structural-textural characteristics of sulfide minerals on their leaching from polymetallic concentrates with sulfuric acid and hydrogen peroxide solutions. The polymetallic concentrate was obtained by flotation of polymetallic ore from the Rudnik deposit in Serbia. X-ray diffraction (XRD), qualitative and quantitative mineralogical, scanning electron microscopy (SEM/EDX), and chemical analyses were used to characterize the polymetallic concentrate and leach residue. The polymetallic concentrate contained chalcopyrite, galena, sphalerite, pyrrhotite, and quartz. The total content of sulfide minerals was 69.5%, and the occurrence of free sulfide mineral grains was about 60.9%. The comprehensive thermodynamic analysis was done by HSC Chemistry (R) package 9.9.2.3 to determine optimal experimental leaching conditions. Chalcopyrite, sphalerite, and pyrrhotite oxidized during leaching, and dissolution occurred. The oxidized galena remains in the solid residual as insoluble anglesite. Also, elemental sulfur and unleached minerals of copper, zinc, and iron were found in the leach residues. It was found that the structural assembly of sulfide minerals in the leach residue is very favorable and that undissolved sulfide grains are primarily present in free form. Accordingly, there was no reason to reduce the leaching rate with time. The presence of elemental sulfur and anglesite formed in the leaching process and precipitated on the surface of mineral grains was confirmed by XRD, quantitative and qualitative mineralogical analysis, and SEM/EDX.

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.

Fe3+/Cr3+/ekspandirani vermikulit (Fe2O3 / Cr2O3 / EV) pripremljen je metodom in-situ. Kompozitni
i osnovni materijal karakterisan je Furijeovom transformacijom infracrvene spektroskopije (FTIR),
rendgenskom difrakcijom (XRD), skenirajućom elektronskom mikroskopijom (SEM), a određeni su i:
specifična površina BET-om (SBET), kapacitet katjonske izmene (CEC) i pH tačke nultog
naelektrisanja (pHPZC). Adsorpciona svojstva Fe2O3 / Cr2O3 / EV i EV ispitivana su u šaržnom
sistemu na pH blizu pHPZC za uklanjanje Ni (II) iz vode. Uzimajući u obzir parametre procesa kao
što su vreme kontakta, masa adsorbenta i temperatura određeni su tip adsorpcije, termodinamički i
izotermski parametri (Lengmir i Frojndlih) i parametri brzine adsorpcije. Rezultati kinetičkih studija
dali su dobre korelacije sa modelom pseudo - drugog reda i Veber - Morisovim modelom. Uzimajući
u obzir činjenicu da je EV imao niske vrednosti CEC i specifične površine, dobijeni kompozit ima
umerenu adsorpcionu sposobnost (22,9 mg/g).",

AB  - This paper present results of experimental investigations of metallic calcium production from Serbian carbonate raw materials by aluminothermic process and the basic operating parameters of the particular technological phases. The limestone with high content of Mg, Na and K was used in the study. X-ray analysis reveals that samples contain mainly calcite with small amount of dolomite. The DTA/TG analysis of the limestone samples from site “Čačak” (samples C I and C II) and chemical composition of limestone samples are presented in the graphical abstract. At DTA curves of both C I and C II samples sharp endothermic peaks are noticed, related to the dissociation process followed by the endothermic heat effect. Since the DTA curves show only one clearly defined peak, it can be concluded that the calcium carbonate is solely present in the raw materials in the form of calcite, while aragonite is not present. At first, the effects of temperature, time and granulometry on the calcium carbonate calcination were examined. The dissociation process was completed in 10–15 min at 1200 °C, and the dissociation rate increased with decreasing particle size down to 5 mm. Afterwards, the aluminothermic reduction process of calcium oxide was investigated. At a temperature of 1200 °C and vacuum of at least 3 kPa, the reduction process was completed within 2 h. The chemical composition of calcium oxide and metallic calcium showed increased content of magnesium oxide and alkaline oxides (especially sodium).

AB  - Adsorbents based on magnetic materials are the subject of numerous researches. Beside good magnetism and functional surface, manganese ferrite is unstable and prone to form low mechanical strength agglomerates, which necessitate its deposition on the substrate surface. Expanded vermiculite outer surfac, is a useful medium for the deposition of nanoparticles whereas intercation layer is suitable for holding cation species (distance of 2:1 layers may be greater than 10 Å). Due to its relatively high surface area, cation exchange capacity and natural abundance of vermiculite, this mica mineral and its composites could be valorized as potentially low-cost adsorbents. In this study, manganese ferrite/expanded vermiculite (MnFe2O4/EV) composite was prepared by in-situ method. Deposited manganese ferrite particles on the surface of EV were formed in the solvothermal reaction using suitable reagents. Both composite and base material are characterized by Fourier transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRPD), scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) specific surface area (SSA), cation exchange capacity (CEC) and pH point of zero charge (pHPZC) determination. The adsorption properties of MnFe2O4/EV and EV have been investigated in a batch system at pH close to the pHPZC for the removal of Ni (II) from water. Considering process parameters such as contact time, adsorbent dosage and temperature: adsorption type, isotherm parameters (Langmuir and Freundlich) and rate of adsorption parameters were determined. Results of the kinetic studies gave fine correlations with pseudo – second order and Weber – Morris model. Taking into consideration fact that EV had low CEC values and SSA, obtained composite have high adsorption capacity (more than 30 mg Ni g-1). Also, X-ray diffractograms showed alteration of biotite vermiculite (formed during solvothermal action) into phlogopite (formed after adsorption process and aging). The methodology applied in this work may be utilized for the fabrication of other ferrite spinels, perovskites and other oxide systems.

AB  - Mould powder is essential for the reliable operation of the continuous casting system and the quality
of the cast steel. The very responsible roles of mould powder are fulfilled by selecting combinations
of components that affect physicochemical properties of the resulting liquid slag, which lubricate the
walls among the crystallizer and slab. The contribution of mould powder refers to the range of
melting temperature and speed and the viscosity of glassy or crystalline slag and formation
temperature. These connections are the research subject in this paper, emphasizing the functional
dependence of viscosity and liquidus temperature of mould powder with its material composition.
This research investigates the impact of basicity, alkali oxides (Na2O and K2O), and carbon-free
content on viscosity and liquidus temperature of mould powder in the continuous casting process.
The liquidus temperature of mould powder was obtained empirically after a year of experimental
examination, and viscosity was determined using several models. Based on experimental
investigation, we show empirical parameters for equitation of liquidus temperature of mould
powder. Also, using established equations, we presented isolines for viscosity and liquidus
temperature with experimental parameters.

AB  - Phytomining is a technique that aims to obtain metal(oid)s or their products using hyperaccumulating plant species that grow on substrates rich in heavy metals, but not enough to justify conventional mining. After harvesting, the biomass is combusted and the ash is used as bio-ore for the production of pure metal(oid)s or their salts. Most hyperaccumulating plants accumulate Ni, which occurs naturally in high concentrations in ultramafic soils. A large number of Ni hyperaccumulators are found in the genus Odontarrhena, which is most commonly used in phytomining studies. In order to obtain the largest amounts of Ni and the salts of the higher purity, it is necessary to choose the most suitable ash processing treatment. This study shows results of obtaining Ni salts from the ash of Odontarrhena muralis by hydrometallurgical process in the form of ammonium nickel sulfate hexahydrate, Ni(NH4)2(SO4)2x6H2O - (ANSH). Odontarrhena muralis from ultramafic sites at West Serbia accumulates Ni at concentrations of 3300 mg kg-1 and is a good candidate for the phytomining process. By biomass combustion, during which biomass weight decreases for 92.7%, ash was obtained as a suitable raw material for Ni extraction. Out of gained mass of crude ash, 11,71% was yielded as ANSH crystals.The obtained purity of ANSH was 73%, which is slightly lower compared to similar studies, but good enough to show the potential for phytomining application. By optimizing the purification process that precedes precipitation of the ANSH crystals, the purity of recovered crystals can be additionally increased, influencing the economic feasibility of the process. Moreover, by selecting appropriate agronomic measures, it is possible to obtain biomass of O. muralis with increased concentration of Ni in aboveground parts, which would increase the initial concentration of Ni in bio-ore that is entering the extraction process.

AB  - Phytomining is a new promising technique that is based on using hyperaccumulating plants which biomass is utilized as a bio-ore for metal extraction. The Ni-hyperaccumulating species Odontarrhena muralis is widely distributed on ultramafic soils in Serbia, and could be a promising candidate for Ni agromining. In the present study, efficiency of a hydrometallurgical process for Ni recovery using biomass of O. muralis wild population through the synthesis of Ni salts from plant ash in the form of ammonium nickel sulfate hexahydrate, Ni(NH4)(2)(SO4)(2) 6H(2)O-(ANSH) was assessed. The average Ni content in the plant from ultramafic sites in West Serbia was up to 3.300 g kg(-1). The mass yield of ANSH crystals from the crude ash was similar to 12 % with the average purity of 73 % were obtained. By optimizing the purification process before precipitation of ANSH crystals, it is possible to obtain salt crystals of higher purity, which increases the economic profitability of this process. The results of this preliminary study on wild population of O. muralis show the increased potential for implementation of phytomining practices as an alternative way of Ni extraction on ultramafic sites in Serbia.
