AB  - During the conventional roast–leach–electrolysis (RLE) zinc production process,
precipitation of the jarosite-type compounds is widely used to remove iron and other metal
impurities from the solution. Above mentioned compounds, with the general formula
MFe3(SO4)2(OH)6, (M+=NH4, Na, K, Ag, etc.), in addition to iron, contain a high
concentration of Pb, Cd, Cr, As, Zn, In, Ga, Ge as metal oxides and/or sulfates [1].
Consequently, jarosite is considered hazardous yet valuable waste [2]. In addition, every
year around 6-7 million tonnes of jarosite waste is generated globally [3]. Due to large waste
volumes and its chemical characteristics, jarosite requires a lot of storage space and
monitoring. Unfortunately, this type of waste is often landfilled causing serious
environmental problems and irreversible metal and value losses. Hence, an urgent solution
for both managing and utilization/recycling is required, to face needs regarding ecological
demands and circular economy goals.
In this paper, jarosite sludge, as a specific type of hazardous industrial waste, is used
to investigate transformation to the targeted compounds through the comprehensive
thermodynamic analysis and experimental roasting process tests. The roasting was
conducted to transform iron into insoluble hematite (Fe2O3), valuable metals (Zn, Cu, and
In) into water-soluble sulfates, and to keep Pb in the form of water-insoluble anglesite
(PbSO4). The solid residue obtained after roasting was used in leaching tests to further
evaluate the efficiency of the targeted phase transformations.
Theoretical considerations of chemical reactions and phase thermodynamics were
performed using the HSC Chemistry v.9.2.3 software [4] to define potential chemical
reactions, examine the feasibility of the target transformations, and set the limiting reaction
parameters. Further, in the first part of the experimental work, the influence of the roasting
process and reaction parameters on the transformation of jarosite sludge phases into target
compounds was investigated. This included variations in the reaction time, temperature, and
furnace atmosphere influence. The leaching conditions were kept constant (temperature of
25 °C, during 60 min, and solid to liquid ratio of 1/5) to determine the efficiency of phase
transformations in the samples obtained by roasting. Changes in the chemical and
mineralogical composition and microstructure were analyzed using different analytical
methods, including XRD and SEM analysis.
According to the obtained results of the roasting process, it was determined that the
phase transformation of jarosite sludge compounds into targeted insoluble hematite and
water-soluble sulfates occurs at 730 °C, the time required is 60 min in the air (oxidizing) atmosphere of 1-2 [dm3/h]/kg of the input material, which is in accordance with the results
of the theoretical indications. Also, it is experimentally confirmed that the introduction of
sulfate into the roasting atmosphere leads to the incomplete transformation of jarosite and
the formation of the unwanted Fe2(SO4)3. Leaching results of the sample obtained by the
abovementioned optimal roasting conditions show that only 4.5 % of Fe is leached while
the rest remains as solid targeted hematite. Also, more than 75 % of In and more
than 90 % of other targeted metals (Cu and Zn) are leached, indicating the high efficiency
of the roasting process. Phase transformation was confirmed by SEM analysis, showing that
hexagonal crystals of jarosite, dominating in the starting material, were completely replaced
with the globular microstructure of Fe2O3, in the roasted samples. SEM analysis of the
leaching residue also confirmed the absence of the water-soluble sulfates and the presence
of the anglesite as water-insoluble sulfate. The phase composition of the samples is
confirmed by XRD analysis.
This research shows that the proposed process enables the recycling of jarosite through
metal transformation and further utilization. The obtained products can be used in industry,
while the metal ions can be selectively separated from the sulfate solution and returned to the
production streams. This approach contributes to the utilization of jarosite, as hazardous
waste, in order to obtain valuable metals, and generally reduces the negative environmental
impact by decreasing the amount of disposed waste and reducing the need for primary
exploitation.

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.

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,
such as Fe or Cu. The chemical and mineralogical
composition of the initial samples of FJM and FA
was evaluated two standard leaching tests: TCLP
and EN 12457-4, as well as Acid Neutralization
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

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  - 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  - 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  - A simple sol-gel method and external gelatinization method of hollow alumina spheres synthesis were developed in this study. The spheres were modified with polyethyleneimine (PEI) producing PEI-Al2O3 via (3-glycidyloxypropyl)trimethoxy-silane, GLYMO, linker. Characterization results, obtained using XRD and SEM microscopy revealed spherical geometry with a hollow core of PEI-Al2O3 adsorbent. Introduction of a large number of the amino group, 6.9 mmol g(-1), contributes to achieving high adsorption capacities, q(m), of 95.6, 124.9, 61.3, and 125.9 mg g(-1) for Cd2+, Pb2+, As(V), and DCF, respectively, which is obtained by using the Langmuir model. Thermodynamic studies indicated feasible adsorption and higher spontaneity with temperature increase. The kinetic study conveniently modeled using pseudo-second-order (PSO) and Weber-Morris kinetic model, as well as single resistance mass transfer model, indicated a change of the contribution of diffusional processes during adsorption with a dominance of intra-particle diffusion. The fixed-bed column adsorption data, fitted using Bohart-Adams, Clark, Yoon-Nelson, and Thomas models, showed lower capacity in comparison to batch study, and thus clear potential applicability of PEI-Al2O3 was deduced even at a high loading of feed water.

AB  - Srbija ima više nalazišta i aktivnih rudnika polimetaličnih ruda olova i cinka i viševekovnu tradiciju u njihovoj eksploataciji. Sa metalurškom preradom koncentrata cinka počelo se u Srbiji 1955. godine u preduzeću "Zorka", Šabac, a u kombinatu "Trepča", Kosovska Mitrovica 1967. godine. Raspad Jugoslavije, opšte društvene okolnosti i svojinska transformacija doveli su do značajnog opadanja proizvodnje od 1992. godine i do konačne obustave metalurške proizvodnje cinka 1999. godine u "Trepči" i 2002. godine u "Zorki".

AB  - By-products from zinc hydrometallurgy are classified as hazardous waste with strong leaching toxicities. Even though numerous research papers are dedicated to valorizing valuable metals in it, the primary management route is still disposal or partial reuse, such as the Waelz process. Presented experimental research investigates possibilities of sulfidization and further processing as a technologically sustainable route for valuable metals valorization from non-standard jarosite-PbAg sludge. The comprehensive thermodynamic analysis was done by HSC Chemistry(R), through optimizing process parameters, i.e., temperature, sulfur addition, and selection of possible additives. Technological possibility of magnetic separation, flotation, and smelting of sulfidized material was also investigated; the results were below the values that allow practical application, due to the obtained texture of sulfidized jarosite, which does not allow the liberation of minerals. Smelting tests were performed on sulfidized jarosite with sulfur and without and with carbon as additive. By smelting sulfidized jarosite-PbAg sludge with added carbon in sulfidization stage at 1375 degrees C, obtained products were matte, slag, raw lead, and dust in which base, critical, and slag forming components were valorized. Valuable metals were concentrated in smelting products so as to enable further processing, which also could be interesting in the case of treatment of complex, polymetallic, and refractory primary materials, which represent a significant contribution to the circular economy.

AB  - Flotation tailings rich in carbonate minerals from the tailings deposit of the copper mine Majdanpek (Serbia) were applied for neutralization of the water taken from the extremely acidic Lake Robule (Bor, Serbia). Tests conducted in Erlenmeyer flasks showed that after neutralization of the lake water to pH 7, over 99% of aluminum (Al), iron (Fe), and copper (Cu) precipitated, as well as 92% of Zn and 98% of Pb. In order to remove residual Mn and Ag, the water was further treated with NaOH. After treatment with NaOH, all concentrations of the metals in the lake water samples were below discharge limits for municipal wastewater according to the national legislation of the Republic of Serbia. The results of this work suggest that mining waste could be used for active neutralization of the acid mine drainage. The use of the mining waste instead of lime could reduce the costs of the active treatment of the acid mine drainage.

AB  - In ores, chalcopyrite is usually associated with other sulfide minerals, such as sphalerite, galena, and pyrite, in a dispersed form, with complex mineralogical structures. Concentrates obtained by flotation of such ores are unsuitable for pyrometallurgical processing owing to their poor quality and low metal recovery. This paper presents the leaching of chalcopyrite concentrate from the location "Rudnik, Serbia". The samples from the flotation plant were treated with hydrogen peroxide in sulfuric acid. The influences of temperature, particle size, stirring speed, as well as the concentrations of hydrogen peroxide and sulfuric acid were followed and discussed. Hence, the main objective was to optimize the relevant conditions and to determine the reaction kinetics. It was remarked that the increase in temperature, hydrogen peroxide content, and sulfuric acid concentration, as well as the decrease in particle size and stirring speed, contribute to the dissolution of chalcopyrite. The dissolution kinetics follow a model controlled by diffusion, and the lixiviant diffusion controls the rate of reaction through the sulfur layer. Finally, the main characterization methods used to corroborate the obtained results were X-ray diffraction (XRD) as well as qualitative and quantitative light microscopy of the chalcopyrite concentrate samples and the leach residue.

AB  - Since commissioning in 1961, the copper mine Majdanpek, a part of the Mining and Smelting Complex Bor (RTB Bor), produced approximately 378 million tons of flotation tailings. Semiquantitative mineralogical analysis of the flotation tailings revealed significant content of carbonate minerals (approximately 20-25 %), indicating high acid neutralization capacity. Also, approximately 70 % of copper is in the form of the oxide mineral cuprite (Cu2O). Copper can be easily leached from cuprite by using sulphuric acid. The RTB Bor copper smelter generates 8.7 m(3)h(-1) of extremely acidic waste effluent (142.4 kgm(-3) of sulphuric acid, pH - 0.464) with relatively high concentrations of dissolved metals and metalloids (Cu, Fe, Zn, Pb and As). The effluent is currently treated with hydrated lime. The present study focused on application of flotation tailings as a neutralizing agent for acidic effluents. Laboratory experiments followed by computer simulation of the industrial process showed that 99% of the acid can be neutralized with flotation tailings in a series of six reactors resulting in the final copper concentration of 1.55 gL(-1). Benefits of the proposed process are: lower environmental impact of the process and reduced costs of neutralization of the acidic effluent from the copper smelter.

AB  - Jarosite and neutral leaching residue (NLR) are the greatest environmental problems of hydrometallurgical zinc production due to their high quantity and hazardous content. Pyrometallurgical processes, such as the Waelz process, could be applied to recover valuable metals present in this waste. The paper investigates the possibility of forming environmentally stable Waelz slag after the Waelz process of jarosite and NLR. Waelz slag, obtained using CaO as a conventional alkaline additive in the Waelz process, showed high As and Sb release after the EN 12457-4 standard leaching test. Multiphase equilibrium composition calculations indicated that As and Sb were present as volatile and migratory species in the slag. In order to obtain Waelz slag with more stable matrices that would encapsulate and immobilize pollutants, MgO additions to CaO and different cooling conditions of the slag were further investigated. The efficiency of modification in additives composition and cooling conditions was assessed by EN 12457-4 leaching test and chemical and microstructural characterization (XRF and SEM-EDS analyses) of the Waelz slags. The results show that addition of MgO does not reduce the efficiency of the process, even more it increases leaching resistance of the slags. Concentrations of all investigated metals (As, Ba, Cu, Mo, Pb, Sb, Zn) after the leaching test were below defined limits for non-hazardous waste. Microstructural analyses revealed that MgO remained inert during Waelz process, and thus favoring the formation of amorphous stable structure, which was enhanced by increased cooling rate. All investigated Waelz slags with MgO additions are suitable for further use or safe disposal.

AB  - In this paper, the influence of structural and textural characteristics of sulfide
minerals on their leaching from a polymetallic concentrate by sulfuric acid and
sodium nitrate solution is presented. The starting material was Pb–Zn–Cu sulphide
polymetallic concentrate enriched during the flotation of a polymetallic ore
in the ″Rudnik″ flotation plant (Rudnik – Serbia). Leaching experiments were
carried out in a closed glass reactor, which provides stable hermetic conditions
and allows heating at constant temperature. Chemical, XRD, qualitative and
quantitative microscopic and SEM/EDX analyses were used to characterizes
samples of the polymetallic concentrate and leach residue. It was determined that
chalcopyrite, sphalerite, galena, pyrrhotite and quartz were present in the polymetallic
concentrate. The content of sulphide minerals was 69.5%, of which 60.9%
occurred as liberated grains: 88.3% of chalcopyrite, 59.3% of sphalerite, 25.1% of
galena and 51.6% of pirrhotite. The rest of chalcopyrite, sphalerite, galena and
pirrhotite grains were in the forms of inclusions, impregnations, and simple and
complex intergrowths. During the leaching process by sodium nitrate and sulphuric
acid solution, it was shown previously that the leaching rate of sulphide
minerals decreased with time while a part of the sulphide minerals remained in
the leach residue. After leaching at 80 °C for 120 min, the yields were 69.8, 82.7
and 67.1% for Cu, Zn and Fe, respectively. Lead, in the form of insoluble anglesite,
remained in the leach residue. In addition to the anglesite, unleached sulfide minerals
and quartz, elemental sulfur was found in the solid residue. The content of
sulphide minerals was 35% of which 33.7% minerals occur independently. In specific,
54.7% of chalcopyrite, 31.9% of sphalerite, 8.2% of galena and 37.6% of
pyrrhotite appear as separate grains with highly corroded surfaces. Therefore, the
structural assembly of sulphide grains in the polymetallic concentrate is favourable
and it is not the reason for the observed decrease in the leaching rate in the
final process stages. The obtained findings may be explained by the presence of
elemental sulphur that is formed during the reaction and precipitated at the grain
surfaces, thus creating a diffusion barrier for the leach solution.

AB  - The determination of mechanism of the polymetallic concentrate leaching with sulfuric
acid and hydrogen peroxide was done based on the characterization of the starting
concentrate and leach residues. The application of XRD and thermal analysis on the
leaching mechanism determination was done. The phase content of concentrate and leach
residues were determined by X-ray analysis using diffractometer PHILIPS PW-1710. DTA
and TG analysis were performed in air atmosphere up to 1173 K on NETZSH, model 409
EP, device.
The polymetallic concentrate, used in experiments, has the following chemical
composition (in wt. %): Cu-8.92, Zn-8.79; Pb-12.66, Fe-19.80 and S-21.4. X-ray phase
analysis of the concentrate reveals that the sample contains chalcopyrite, sphalerite, galena
pyrhotite and quartz (Fig. a). On Fig. b the DTA and TG curves of polymetallic concentrate
are shown. Curves include two parts: first, a low temperature, which correspond to the
sulfides oxidation (the mass increase on the TG, and exothermic peaks on the DTA); and
second which correspond to the dissociation of sulphates and oxysulphates (the mass loss
on the TG, and endothermic peaks on the DTA).
The phases identified in the leach residue by XRD were elemental sulphur, anglesite,
chalcopyrite, sphalerite, galena pyrhotite and quartz (Fig. c), which confirms that the
elemental sulphur is formed during leaching. In Fig. d the TG-DTA curve of the leach
residue are shown. On DTA curve on the temperature of 118 oC, the endothermic peak as a
result of elemental sulfur melting is clearly visible. Then, in the range of 250-350 oC,
weight loss as a consequence of the oxidation of sulfur to SO2 gas occurs. The loss of mass
due to combustion of sulfur on Fig. d is smaller than the sulfide sulfur which is oxidized
during the leaching process, which indicates that the sulfur from sulfides is oxidised both
to the sulfate and to the elemental form. The mass increase followed by exothermic effects
in the range of 400-700 oC is a result of the oxidation of unleached sulphides in the solid
residues. At temperatures above 720 °C weight loss occurs as a result of dissociation of
sulphate and oxysulphates of lead, zinc, copper and iron with endothermic peaks on the
DTA curve. XRD and DTA/TG studies have contributed in determining the mechanism of
polymetallic concentrate leaching process in the system H2SO4-H2O2-H2O:CuFeS2 + 5/2H2O2 + 5/2H2SO4 = CuSO4 + 1/2Fe2(SO4)3 + 2S0 + 5H2O
(1)
CuFeS2 + 17/2H2O2 + 1/2H2SO4 = CuSO4 + 1/2Fe2(SO4)3 + 9H2O(2)
ZnS + H2O2 + H2SO4 = ZnSO4 + S0 + 2H2O (3)
ZnS + 4H2O2 = ZnSO4 + 4H2O (4)
PbS + H2O2 + H2SO4 = PbSO4 + S0 + 2H2O (5)
PbS + 4H2O2 = PbSO4 + 4H2O (6)

AB  - The analysis of material and energy balance can be done using concept of exergy, which is
a measure of available energy in the system [1]. Exergy losses indicate the place of
degradation in the process; thus, it implies improving of selected process.
The aluminothermic reduction process is an attractive method for immobilization of
hazardous waste, and for utilization of valuable elements from the waste [2]. The exergy
calculation relies on the material and energy balance calculation and standard chemical
exergy of the elements. For the purpose of material, energy, and exergy balance calculation
discrete non-commercial software was developed [3]. The waste materials used in these
calculations are Electric-arc furnace dust (EAFD, mostly Fe and Zn oxides) and the Mill
scale (mostly Fe oxides) [4].
Calculated exergy efficiency for aluminothermic processing of waste was 94.6%. All the
heat released by exothermic reactions was used for producing the iron, the slag and the
crude ZnO dust. Comparing to the conventional carbothermic reduction process in the DC
electric-arc furnace with the same materials (for which exergy efficiency was 56.5%) this
is much higher. The irreversible exergy losses of the aluminothermic process are 398.2
kWh/t of produced iron. The further processing of slag and dust is required, as well as in
the case of the carbothermic reduction process, so that the real value of exergy efficiency
of the process will be somewhat lower than the calculated.

AB  - In this paper, the influence of structural and textural characteristics of sulfide minerals on their leaching from a polymetallic concentrate by sulfuric acid and sodium nitrate solution is presented. The starting material was Pb-Zn-Cu sulphide polymetallic concentrate enriched during the flotation of a polymetallic ore in the "Rudnik" flotation plant (Rudnik - Serbia). Leaching experiments were carried out in a closed glass reactor, which provides stable hermetic conditions and allows heating at constant temperature. Chemical, XRD, qualitative and quantitative microscopic and SEM/EDX analyses were used to characterizes samples of the polymetallic concentrate and leach residue. It was determined that chalcopyrite, sphalerite, galena, pyrrhotite and quartz were present in the polymetallic concentrate. The content of sulphide minerals was 69.5%, of which 60.9% occurred as liberated grains: 88.3% of chalcopyrite, 59.3% of sphalerite, 25.1% of galena and 51.6% of pirrhotite. The rest of chalcopyrite, sphalerite, galena and pirrhotite grains were in the forms of inclusions, impregnations, and simple and complex intergrowths. During the leaching process by sodium nitrate and sulphuric acid solution, it was shown previously that the leaching rate of sulphide minerals decreased with time while a part of the sulphide minerals remained in the leach residue. After leaching at 80 degrees C for 120 min, the yields were 69.8, 82.7 and 67.1% for Cu, Zn and Fe, respectively. Lead, in the form of insoluble anglesite, remained in the leach residue. In addition to the anglesite, unleached sulfide minerals and quartz, elemental sulfur was found in the solid residue. The content of sulphide minerals was 35% of which 33.7% minerals occur independently. In specific, 54.7% of chalcopyrite, 31.9% of sphalerite, 8.2% of galena and 37.6% of pyrrhotite appear as separate grains with highly corroded surfaces. Therefore, the structural assembly of sulphide grains in the polymetallic concentrate is favourable and it is not the reason for the observed decrease in the leaching rate in the final process stages. The obtained findings may be explained by the presence of elemental sulphur that is formed during the reaction and precipitated at the grain surfaces, thus creating a diffusion barrier for the leach solution.

AB  - Simulating the reactions in a complex system can lead to self-sustaining and energy efficient treatment of wastes in recycling promoting manner. In this contribution, the synergic combination of electric arc furnace dust (EAFD), mill scale, and secondary aluminum, in a form of waste foil, was researched aiming to use exothermal energy of reactions and to obtain environmentally favorable products. The secondary aluminum in the form of foil was prepared in different ways in order to develop aluminum surface and to be suitable for aluminothermic reactions. The commercial aluminum powder was used to determine optimal conditions using full factorial experiment design. After that, research was performed on aluminothermic reactions with the aluminum powder obtained from secondary aluminum foils. Results show that the secondary aluminum can be successfully used for a treatment of oxides bearing hazardous wastes in an energy efficient and environmentally friendly manner. The comparative life-cycle assessment revealed several advantages of using the secondary aluminum foil as a reduction agent compared to the conventional recycling of the secondary aluminum foil.

AB  - The results of research on the leaching process of complex sulphide- barite ore were presented in this paper. The leaching process was carried out in a laboratory autoclave by ferric chloride solution. Considering that those minerals are represented in complex structural-textural relationships, it is not possible to extract lead, zinc and copper minerals from ore by flotation methods. The obtained results confirmed possibility of the ore processing directly, by chemical methods. The effect of temperature, time and oxygen partial pressure on the lead, zinc and copper dissolution was studied. The maximal leaching degree was achieved at 100 degrees C and amount of 91.5 % for Pb, 96.1 % for Zn and 60.7 % for Cu). Leaching at temperatures above 100 degrees C is impractical.

These metallurgical wastes consist of a many different phases and elements, making the reaction process complex. Thermo-chemical analysis of the reactions in metal, slag, and gas phases was done, and used for modeling of the mixture composition and energy consumption required for smelting. Modelling was performed with the software named RikiAlC. The crude ZnO, slag, and metal phase were analyzed using the atomic absorption spectrometry (AAS), the optical emission spectrometry with inductively coupled plasma (ICP-OES), the X-ray diffraction (XRD), the scanning electron microscopy (SEM) equipped with energy dispersive spectrometry (EDS), and reflected and transmitted light microscopy. Also, in order to follow the behavior of this process the exhausted gases were monitored. The synergetic effects of the designed mixture may be recognized in minimizing energy consumption for the smelting process, improving the product yield efficiency, and reducing the negative environmental effects.
