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.

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  - This paper explores the possibility of synthesising catalyst supports with improved properties. Alumina foams were produced with the polymer replication technique. Representative high- and low-temperature sintering ceramics were selected. Suitable suspension amounts, the clay addition and sintering temperature were determined. A lower sintering temperature was used for an economic enhancement of the process. The sintering was conducted at the temperatures from 1573 K to 1773 K for 60 min. A comparative analysis of the studied systems shows that the best compressive strength of 6.2 MPa was achieved with the system based on the alpha-Al2O3-25 clay (mass fractions, w/%), polyester foam with 10 PPI, sintered at 1673 K.

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  - 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  - A method of synthesizing Ni-based catalysts supported on alpha-Al2O3-based foams was developed. The foams were impregnated with aqueous solutions of metal chlorides under an air atmosphere using an aerosol route. Separate procedures involved calcination to form oxides and drying to obtain chlorides on the foam surface. The synthesized samples were subsequently reduced with hydrogen. With respect to the Ni/Al2O3 catalysts, the chloride reduction route enabled the formation of a Ni coating without agglomerates or cracks. Further research included catalyst modification by the addition of Pd, Cu, and Fe. The influences of the additives on the degree of reduction and on the low-temperature reduction effectiveness (533 and 633 K) were examined and compared for the catalysts obtained from oxides and chlorides. Greater degrees of reduction were achieved with chlorides, whereas Pd was the most effective modifier among those investigated. The reduction process was nearly complete at 533 K in the sample that contained 0.1wt% Pd. A lower reduction temperature was utilized, and the calcination step was avoided, which may enhance the economical and technological aspects of the developed catalyst production method.

AB  - The paper presents an improved process for recycling of silver-plate brass housing. Silver and copper are recovered with a purity of 99.99 % and 99.90 %, respectively, with the aim of obtaining materials of higher value using additional procedures based on the same process and equipment. The novel approach with subsequent electrorefining yields copper of 99.99 % purity with BS EN 1978:1998 (Cu-CATH-1) quality and is referred to as LME grade A. Additional processing of silver results in superfine, micro-sized Ag powder with partie size from 0.14 to 1.13 mu m and purity of 99.999 %. Copper electrorefining tests were performed using 1.50 dm(3) of synthetic electrolyte in a 2 dm(3) electrolytic cell. Effects of current density and electrolyte composition were investigated. Optimal current density for the first and second refining was 120 A/m(2) and 200 A/m(2), respectively. Additional refining of silver was performed by chemical reduction from an aqueous solution. Optimal results were obtained with ascorbic acid as a reduction agent in concentration of 0.1 mol/dm(3) and polyvinylpyrrolidon as a protective agent in concentration of 2 % by mass. The investigation results could be adopted into production.

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.

abstract = "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.",
