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  - 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

AB  - Zinc is extracted from sphalerite and complex concentrates by pyrometallurgical or hydrometallurgical processes, whereby the hydrometallurgical processes
have received considerable attention in recent years. Thair application provide
better metal recoveries and reduced emission of gaseous and toxic agenses in the
environment. This paper studies the leaching process of the sphalerite with sodium
nitrate in sulphuric acid solution. Chemical reactions of leaching and their thermodynamic probabilities are predicted based on the calculated Gibbs energies and
analysis of E-pH diagrams. Thermodynamic analysis, experimental data, chemical,
XRD, TG/DTA, and SEM/EDX analyses for the phases present in both the complex
concentrate and leach residue were performed to determine the leaching process.
Elemental sulphur is the main solid product of reaction, and a minor amount of
sulphide sulphur is oxidized to sulphate during the leaching. It also indicates that
the sulphur precipitated at the particle surfaces, and slowed down the rate of the
leaching process.

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

AB  - Proizvodnja obojenih metala iz sekundarnih sirovina daleko je jeftinija od njihove proizvodnje iz primarnih sirovina, prvenstveno zbog manje potrošnje energije. Pored toga, reciklažom obojenih metala iz sekundarnih sirovina racionalnije se koriste prirodni resursi i smanjuje količina otpadnih materijala, čime se direktno štiti životna sredina. Sekundarne sirovine obojenih metala nastaju u procesu proizvodnje i prerade metala do njihove ugradnje u gotove priozvode i izbacivanjem tih proizvoda iz upotrebe usled njihove dotrajalosti ili tehnološke zastarelosti. U zavisnosti od vrste sekundarne sirovine, koriste se različiti postupci pripreme i metalurške prerade. Pojedine se veoma jednostavno recikliraju pretapanjem u metalurškim agregatima, dok druge moraju proći komplikovane operacije pripreme pre metalurške prerade.
AB  - Production of non ferrous metals from secondary raw materials is far less costly than its production from primary raw materials, due to lower energy consumption. Besides, by recycling of non ferrous metals from secondary raw materials, the natural resources are saved and the amount of waste materials is reduced, directly protecting the environment. The secondary raw materials can originate in metal production and treatment, accompanied by their incorporation into the final product and its elimination due to amortization. The different methods of preparation and metallurgical treatment are used depending on secondary raw materials type. Some of them are very easy to be recycled by remelting in metallurgical furnace, while others must pass through complicated preparation before metallurgical treatment.

AB  - Refractory sulphide-barite ore was reduced with carbon in order to release lead, zinc, and copper sulphide from barite-pyrite base. Mineralogical investigations showed that due to the complex structural-textural relationships of lead, copper and zinc minerals with gangue minerals, it is not possible to enrich the ore using the conventional methods of mineral processing. The influence of temperature and time was studied to optimize the conditions, and to determine the kinetics of the barite reduction. The maximum removal of barite from ore was 96.7% at 900oC after 180 min. Chemically controlled kinetic model showed the best compliance with the experimental data. An activation energy of 142 kJ/mol was found.

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.

Processing of such mixed ores by the existing concentration technologies leads to a substantial copper losses ( LT 60%). Reduction of 'oxide copper', by acid leaching prior the flotation concentration, can increase the overall copper efficiency up to more than 70% in the single-stage leaching, achieving an efficiency in the flotation concentration stage higher than 75%. Based on the performed experimental results, the flow sheet for processing of the mixed oxide-sulfide copper ore is proposed.

AB  - U procesu rafinacije bizmuta, hlorovanjem legure Bi-Pb (bizmut pena) Kroll-Bettertonovim procesom kao međuprodukt pojavljuje se olovo-hlorid. Predmet ovog rada je valorizacija olova iz pomenutog međuprodukta postupcima aluminotermije i cinkotermije. Pored olova pomenutim postupcima dobijaju se glinica tehničkog kvaliteta (aluminotermija) i cinkhlorid (cinkotermija). Za ispitivanja su korišćeni sekundarni aluminijum i cink različite krupnoće. Ispitan je uticaj temperature, vremena, krupnoće reducenta i brzine mešanja (cinkotermija) na stepen iskorišćenja olova i definisani optimalni parametri procesa. Stepen iskorišćenja sirovog olova (98%Pb) iznosi 95-98% u slučaju aluminotermije i 85-90% u slučaju cinkotermije. Dobijeno sirovo olovo prerađuje se u rafinerijama olova. Glinica tehničkog kvaliteta ima primenu u keramičkoj industriji dok se cink- hlorid hidrometalurški tretira u cilju dobijanja 50%-nog rastvora cink-hlorida.
AB  - In the refinement process of bismuth by chlorinating of Bi-Pb alloy (Kroll-Betterton process) as a by-product lead chloride is formed. This study was focused on the lead valorization from PbCl 2 by aluminothermic and zincothermic reduction. Besides lead, as a main product, during aforementioned process technical grade alumina (aluminothermic reduction) and ZnCl2 (zincothermic reduction) were also obtained. The secondary aluminium and zinc of different granulometry were used as a reducent. The effect of temperature, time, granulometry of reducents and stirring speed (zincothermic reduction) on the lead recovery was investigated. Based on the experimental results, the optimal process parameters were defined. Recovery of crude lead (containing 98%Pb) was in the range 95-98% for aluminothermic reduction and 85-90% for zincothermic reduction. The crude lead can be further processed in lead smelters. Technical grade alumina was used in ceramic industry, wile zinc-chloride is suitable for hydrometallurgical treatment giving 50 % solution of zinc-chloride as the final product.

AB  - With the recently increased use of magnesium alloys, especially in the automotive industry, a large quantity of generated waste, based on magnesium alloys, is expected. Such a waste often contains many impurities such as oil, paint, moisture, non-metallic fractions, oxides, Cu, Fe, etc. In this paper, two different methods for extracting magnesium from a highly contaminated waste are presented: the recycling of magnesium with flux and with the vacuum-distillation process. In addition, we present the process of pre-treating the contaminated magnesium waste that has proved to be a very important step in the recycling process for both economic and environmental reasons. The processing of post-consumer and contaminated magnesium scrap is described with a diagram, providing a sustainable and environmentally friendly procedure for the treatment of such wastes.

AB  - Eksperimentalnim istraživanjima su definisani kako tehnološka šema dobijanja kalcijuma iz krečnjaka aluminotermijskim procesom tako i osnovni radni parametri pojedinih tehnoloških faza. Uzorci krečnjaka koji su korišćeni u radu imaju visok sadržaj Mg, Na i K. Rendgenska analiza je pokazala da uzorci uglavnom sadrže kalcit i u manjoj količini dolomit. Na početku je ispitan uticaj temperature, vremena i granulometrijskog sastava na kalcinaciju kalcijum-karbonata. Vreme trajanja procesa disocijacije je 10-15 min na 1200 °C i povećava se sa smanjenjem veličine čestica do 5 mm. Nakon toga, ispitana je aluminotermijska redukcija kalcijum-oksida. Na temperaturi od 1200 °C i vakuumu od 3 KPa proces redukcije se završava za 2 h. Analiza hemijskog sastava kalcijum-oksida i kalcijuma pokazuje povećan sadržaj magnezijum-oksida i oksida alkalnih metala, posebno natrijuma.
AB  - We present experimental investigations that define both the technological scheme of calcium production from limestone 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 the samples contain mainly calcite with small amount of dolomite. 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 completed within 2 h. The chemical composition of calcium oxide and calcium showed increased content of magnesium oxide and alkaline oxides (especially sodium).

AB  - During the chalcopyrite leaching by sodium nitrate and sulfuric acid solution, leaching rate decreases with increasing the time and a part of chalcopyrite mineral grains remains in the leach residue. In chalcopyrite concentrate, 95.5 % of chalcopyrite mineral occurs as in liberated grains, and the rest is in association with gangue minerals, which is very favorably from the aspect of hydrometallurgical treatment. Complex forms, like impregnations and complex intergrowths, do not exist. After experiments carried out, leaching of copper achieved 84 % at temperature 80 degrees C and time 240 min. In the all leach residues, 97 % chalcopyrite mineral grains occur as liberated with highly corroded surfaces. Therefore, the structural assembly of chalcopyrite grains is favorable and no reason to reduce the leaching rate in the final stage of reaction. Reason for this is elemental sulfur, which was formed during the reaction, precipitated at the particle surfaces, and slowed down the leaching rate in the final stage of leaching process.

AB  - At the contact surface between the liquid metal and the mold wall a number of chemical and thermodynamical reactions were taken. The products of those reactions are spread out on both the sides, i.e., in the solidified metal or into the mold wall. The processes which took place in the casting mold-here made from sand mix, during the pouring of liquid metal, solidification and cooling down to room temperature, are pretty complex. The thermodynamic reactions at the contact surface of liquid metal/sand mold in the process of castings forming are discussed in this paper. Experiments were performed in molds made by CO2 sand casting process. As a pouring metal we used steels from an ordinary production program of a steel foundry, exactly it was the steel GS 50CrMo4, assigned by DIN. Some results obtained in our investigations during studying those processes are shown here.

AB  - Main resources of tin secondary raw materials are: residual tin-plates and by-products from their production (tin slags, sludges and sponges), metallic packings, lead-tin slags and alloys, amortised coolers from cars etc. The technological procedure for their processing includes two basic stages: pretreatment of the scrap and its metallurgical processing. The tin-plated cans pretreatment is a very important phase and it includes the following operations, cans collection, sorting, washing, crushing, warnish removal etc. Due to the easier collection and lower grade of impurities, the pretreatment of the waste tin plates is simpler in comparison with the tin-plated cans. The processing of the prepared scrap, can be carried out in two ways. In one way, the processing consists of chlorination treatment, electrolytical dissolution and precipitation, while in the other way alkaline leaching and electrolysis are employed. The processing of the tin slags, sludges and sponges can be carried out using reductional smelting process and refining of obtained secondary tin.

AB  - Catalysts based on nickel, as active component, exhibit suitable properties in various heterogeneous catalysis processes; however, they quickly deactivate due to deposits formation during exploitation and sintering at elevated temperatures. Considering that catalysts with several catalytic components possess enhanced catalytic properties, in present study the influence of temperature, time and additives (PdCl2, FeCl2 and CuCl2) on the reduction degree of nickel(II)-chloride by hydrogen have been investigated. The objectives of the study were selection of an appropriate catalytic activity modifier and development of a new synthesis method for nanocomposite catalysts production, which are characterized by enhanced properties compared to the commercial Ni/Al2O3 catalysts. Obtained experimental results clearly indicate that the best effect was achieved with addition of 0.1 wt. % PdCl2, whereby NiCl2, reduction degree was 58.16% at 653 K and Pd significantly increased the reduction rate. According to the obtained results., new technological synthesis method of nanocomposite Ni-Pd/Al2O3 catalysis was proposed, where Ni and Pd. as catalytically active components, are homogeneously dispersed in monolithic Al2O3 based ceramic foam.

AB  - During the casting of metals at the interface between metal and mould, or contact surface metal-mould, some chemical reactions occur. Reaction products penetrate or move toward the mould as well as toward the castings. In this work the chemistry at the contact surface between the metal and mould was studied. The objective of the work was better understanding of the chemical reactions that occur, at the interfaces, during the casting processes. All experiments were performed, both, on a laboratory and industrial scale, using the steel samples DIN G-X 120Mn 12, the steel samples came from the steel casting industrial plant production list. The moulds were made using the CO2 procedure. Some active components were added to the mould mixture. During the casting process, while liquid metal enter into the mould vacancy, a kind of intensive reaction of liquid metal with quartz sand and added active components occur thus forming a new chemical compounds. These Compounds have an important influence on the steel castings quality, and consequently on the production economy.

AB  - Interest for application of hydrometallurgical processes in a processing of complex sulphide ores and concentrates has increased in recent years. Their application provides better metal recoveries and reduced emission of gaseous and toxic ageneses in the environment. The kinetics and mechanism of sphalerite leaching from complex sulphide concentrate with sulphuric acid and sodium nitrate solution at standard conditions was presented in this paper. The influences of temperature and time on the leaching degree of zinc were investigated and kinetic analysis of the process was accomplished. With temperature increasing from 60 to 90oC, the zinc leaching increased from 25.23% to 71.66% after 2 hours, i.e. from 59.40% to 99.83% after 4 hours. The selected kinetic model indicated that the diffusion through the product layer was the rate-controlling step during the sphalerite leaching. The activation energy was determined to be 55 kJ/mol in the temperature range 60-90oC. XRD, light microscopy and SEM/EDX analyses of the complex concentrate and leach residue confirmed formation of elemental sulphur and diffusion-controlled leaching mechanism.

AB  - Zinc is a widely applicable metal and therefore the different composition and form of zinc waste is generated. The most important waste material generated in production and processing of zinc is scrap metal of zinc and its alloys, as well as slag, dust and sludge from the production and processing of cathode zinc and zinc alloys. In terms of processing technology, there are different applied procedures depending on the type of raw material. The processing of waste zinc and its alloys is pyrometallurgical and it is based on remelting of dry and degreased raw materials, with alloying during melting to correct the composition. Zinc dust and sludge are processed by Waelz procedure, where the zinc-oxide is obtained and further being processed usually by hydrometallurgical procedure. The zinc and brass slag are grinded, followed by separation metal and oxide components. Large, predominantly metal fraction is being directly melted to obtain zinc or brass. Small, predominantly oxide phase is subjected to hydrometallurgical treatment for zinc valorization.

AB  - U radu su prikazani rezultati ispitivanja luženja halkopiritnog koncentrata rastvorom sumporne kiseline u prisustvu natrijum-nitrata. Izračunate standardne vrednosti Gibsove energije reakcija luženja i analiza E-pH dijagrama stabilnosti potvrdili su mogućnost luženja bakra i železa iz halkopiritnog koncentrata u ispitivanim uslovima. U oksidacionim uslovima pri niskoj vrednosti pH bakar prelazi u rastvor kao Cu2+, a železo kao Fe2+ i Fe3+. Rendgenska difrakciona i termijska analiza (TG/DTA) čvrstih ostataka dobijenih pri različitim uslovima luženja, pokazuju prisustvo halkopirita i elementarnog sumpora, čime je potvrđeno predviđanje da se sulfidni sumpor oksidiše do elementarnog oblika. Skenirajućom elektronskom mikroskopijom (SEM/EDX) utvrđeno je da se nastali sumpor taloži po površini halkopiritnih mineralnih zrna i usporava reakciju u kasnijoj fazi luženja.

AB  - In this work, the process of the chalcopyrite leaching in sulphuric acid solution was investigated. Sodium nitrate was used as oxidant in the leaching process. Chemical reactions of leaching and their thermodynamic possibilities are predicted based on the calculated Gibbs energies and analysis of E-pH diagrams. The negative values of the Gibbs energy show that all chemical reactions are thermodynamically feasible at atmospheric pressure and in a temperature range 25-90°C. At high electrode potential and low pH values, Cu2+, Fe2+ and Fe3+ exist in water solutions. The increase of temperature reduces the probability of Fe3+ existence in the system. The chalcopyrite concentrate, enriched in the 'Rudnik' flotation plant, with 27.08% Cu, 25.12% Fe, 4.15% Zn and 2.28% Pb was used in the work. XRD and DTA analysis of the concentrate reveals that the sample contains mainly the chalcopyrite with small amount of sphalerite. For the description of the reaction of leaching process the leach residuals, obtained at different conditions, were chosen for XRD, TG/DTA and SEM/EDX analyses. The elemental sulphur and chalcopyrite phases identified in leach residuals confirm our prediction that the elemental sulphur is formed during the leaching process. Accordingly, elemental sulphur is the main product of the reaction, while a minor amount of sulphide sulphur is oxidized to sulphate during the leaching. The sulphur formed during the reaction was precipitated at the particle surfaces, and slowed down the leaching rate in the final stage of leaching process. In the initial stage, the reaction rate was controlled by the surface reaction. The mechanism, latter has been changed into a diffusion controlled one.
