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  - This paper aims to determine the potential of volcanic rock found in Etna valley as an adsorbent of heavy metals in anionic form (chromates, arsenates, and selenates). Characterization of the volcanic rock was done with chemical methods (AAS, AES, gravimetric analysis, XRF), physicochemical methods (XRD, FTIR, SEM, DTA, DTG) and physical methods (porosity measurement, Microscopy in transmitted light). Also, equilibrium adsorption capacity was determined. All the results of adsorption capacity were satisfying considering the mineral composition, granulation, and porosity. The removal efficiency of chromates was the biggest (above 30 %) with adsorption capacity of 15.6 mg Cr g(-1). The lowest adsorption efficiency was with the selenates, approximately 18 %.

abstract = "This paper aims to determine the potential of volcanic rock found in Etna valley as an adsorbent of heavy metals in anionic form (chromates, arsenates, and selenates). Characterization of the volcanic rock was done with chemical methods (AAS, AES, gravimetric analysis, XRF), physicochemical methods (XRD, FTIR, SEM, DTA, DTG) and physical methods (porosity measurement, Microscopy in transmitted light). Also, equilibrium adsorption capacity was determined. All the results of adsorption capacity were satisfying considering the mineral composition, granulation, and porosity. The removal efficiency of chromates was the biggest (above 30 %) with adsorption capacity of 15.6 mg Cr g(-1). The lowest adsorption efficiency was with the selenates, approximately 18 %.",

AB  - Modern industrial product design implies presence of many different materials. Consequently, in the recycling process, shredding and separation procedures are applied. However, all materials cannot be completely separated; therefore, there is a contamination in the recycling streams. The quality of the materials streams can be reduced in each of the following recycling steps. These qualitative losses cannot be described by material balance. This paper presents the concept of exergy as a measure of quality losses, and gives the methods for the calculation of the exergy content and the exergy loss. Losses attributed to the recycling or material losses, material contamination losses and dilution requirements can be used as indicators for the materials quality loss as well as for the resource efficiency in the production systems. In this paper, the example of calculations on the steel scrap is presented.

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  - 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 impact of various time-defendant factors on the recycling rate of end-of-life vehicles (ELV) in Republic of Serbia was investigated. Statistical distribution of the frequency of the number of ELV in the year of dismantling depending on the year of production of ELV is designed using the two-parameter Weibull distribution function and MATLAB software, based on a real time data. Obtaining the time-dependence of Weibull parameters, a statistical distribution of frequency of the number of ELV in the coming period in Serbia was simulated. These results in combination with amount of materials in the most abundant cars in Serbia were used to simulate the overall amount of materials, which are available for recycling, in the coming period. These results are essential for automotive recycling industry management, particularly for shredders, dismantlers and metal pre-processors.

AB  - The objects of this investigation were the comparative kinetic analysis of the NiO and NiCl2 reduction by hydrogen during an induction period and elimination of the calcination during the synthesis of Ni/Al2O3 catalysts. The effect of temperature and time on NiO and NiCl2 reduction degrees was studied. Avrami I equation was selected as the most favorable kinetic model and used to determine activation energy of the NiO and NiCl2 reduction for the investigated temperature range (623-923 K) and time intervals (1-5 minutes). The investigation enabled reaching conclusions about the reaction ability and rate of the reduction processes. Afterward, Ni/Al2O3 catalysts were obtained by using oxide and chloride precursor for Ni. The catalysts were supported on alumina-based foam and prepared via aerosol route. Properties of the samples before and after low-temperature hydrogen reduction (633 K) were compared. Obtained results indicated that the synthesis of Ni/Al2O3 catalysts can be more efficient if chloride precursor for Ni is directly reduced by hydrogen during the synthesis process, without the calcination step. In addition, Ni-Pd/Al2O3 catalysts with different metal content were prepared by using chloride precursors. Lower reduction temperature was utilized and the chlorides were almost completely reduced at 533 K.

AB  - Procedures for copper secondary raw materials processing include two basic stages: pretreatment of the copper waste and its further metallurgical processing. For copper waste pretreatment technology, there are different applied procedures depending on the type of raw material.

AB  - Present work is focused on the copper (I) sulphide leaching with sodium chloride in hydrochloric acid solution and with introduction of gaseous oxygen. Chemical reactions of leaching and their thermodynamic probabilities are predicted based on the literature data and products which were formed during the process and the overall leaching reaction was defined. The influence of temperature and time on the leaching degree of copper was experimentally determined. The quantity of dissolved copper increases with the increase of both investigated parameters. Elemental sulphur was formed as the main leaching product, precipitated at the particle surfaces and chloride ions have a role to disrupt the creation of this passive layer.

AB  - Besides iron ore, the main raw material of iron and steel production is steel scrap. This paper presents the quality and sources of creation the iron and steel scrap and estimation of their creation in the future. The content of impurities and trace elements to the scrap is very important and influencing to the quality of the obtained steel. Alloyed steel scrap known composition can often be used as an addition to a metal charge for steel production of the desired composition. Considering the steel scrap formation, the three major groups are elaborated: own scrap or circulation scrap, processing scrap and amortization scrap. The balancing model for estimating of steel scrap creation is based on the calculating the coefficients of the generation circulation, processing and amortization scrap, which are used as the basis for successful modelling.

AB  - Materials for recycling always contain a certain degree of contamination. The presence of impurities i.e. contamination in the recycling streams causes a change in the composition of the original materials to recycle. As a result, the quality of materials can be reduced in each successive step of recycling. In addition, the resources of lower quality are produced from the resource flows which had a higher quality in their original form. This kind losses of quality cannot be measured by mass balance, as well as the quality degradation not only can display measurements of mass. For the calculation of all losses caused by recycling contaminations, all further recycling processes required to return the materials back into resource cycles must be included. The method for calculating the exergy content and exergy losses of metal solutions during recovery and recycling is presented in this paper. The losses attributed to recycling, namely the material losses, the contamination losses with other metals, and the consequent need for dilution can be used as indicators of the quality loss of materials and of the efficiency of resource use in product systems. Therefore, exergy is proposed here as a measure of the efficiency of resources use. This paper presents calculations of exergy losses during recycling shown in the case of aluminum waste.
AB  - Materijali za recikliranje uvek sadrže izvestan stepen nečistoća. Prisustvo nečistoća tj. kontaminacija u reciklažnim tokovima izaziva promenu u izvornom sastavu materijala za reciklažu. Usled toga, kvalitet materijala može se smanjivati u svakom narednom koraku reciklaže. Pored toga, resursi nižeg kvaliteta proizvedeni su iz resursnih tokova koji su u izvornom obliku imali viši kvalitet. Ovakvi gubici kvaliteta ne mogu da se mere masenim bilansima, isto kao što se degradacija kvaliteta ne može prikazati samo merenjem mase. Za proračun svih gubitaka prouzrokovanih reciklažnom kontaminacijom, svi dalji procesi reciklaže potrebni da bi se materijali vratili nazad u resursne cikluse moraju biti uključeni. U ovom radu prikazan je metod za izračunavanje eksergijskog sadržaja i eksergijskog gubitka metalnih rastvora u toku iskorišćnja i reciklaže. Gubici pripisani reciklaži ili tačnije materijalni gubici, gubici usled kontaminacije drugim metalima i posledično potreba za razblaživanjem, mogu se koristiti kao indikatori gubitka kvaliteta materijala i efikasnosti korišćenja resursa u proizvodnim sistemima. Dakle, ovde je eksergija predložena kao mera efikasnosti korišćenja resursa. U radu su proračuni eksergijskih gubitaka tokom reciklaže prikazani na primeru aluminijumskog otpada.

AB  - During floatation of polimetalic ores, in addition to selective concentrates there is a collective sulphide concentrate due to the presence of small mineral types and their complex inter-relations. The existing metallurgies capacities cannot process collective concentrates and therefore our research was focused on a possibility to process the concentrates by leaching with sulphuric acid in the presence of sodium nitrate as an oxidant. A part of research related to the leaching of zinc from polimetalic concentrate in the abovementioned conditions comprises the following phases: thermodynamic analysis of possible leaching reactions, characterization of polimetalic concentrate, investigation of the temperature and time effects on zinc leaching and kinetic analysis of experimental research.
AB  - Pri flotaciji polimetaličnih ruda, pored selektivnih koncentrata, često nastaje kolektivni sulfidni koncentrat zbog prisustva sitnih mineralnih vrsta i njihovih kompleksnih međusobnih odnosa. Postojeći metalurški kapaciteti nisu u mogućnosti da vrše preradu kolektivnih koncentrata, pa su naša istraživanja bila usmerena na ispitivanje mogućnosti njihove prerade luzenjem sumpornom kiselinom u prisustvu natrijum-nitrata kao oksidansa. U ovom radu je prikazan deo ispitivanja vezan za luženje cinka iz polimetaličnog koncentrata и pomenutim uslovima i obuhvata sledeće termodinamičku analizu mogućih reakcija luženja, karakterizaciju polimetaličnog koncentrata, ispitivanje uticaja temperature i vremena na izluženje cinka i kinetičku analizu eksperimentalnih ispitivanja.

A part of research related to the leaching of zinc from polimetalic concentrate in the abovementioned conditions comprises the following phases: thermodynamic analysis of possible leaching reactions, characterization of polimetalic concentrate, investigation of the temperature and time effects on zinc leaching and kinetic analysis of experimental research., Pri flotaciji polimetaličnih ruda, pored selektivnih koncentrata, često nastaje kolektivni sulfidni koncentrat zbog prisustva sitnih mineralnih vrsta i njihovih kompleksnih međusobnih odnosa. Postojeći metalurški kapaciteti nisu u mogućnosti da vrše preradu kolektivnih koncentrata, pa su naša istraživanja bila usmerena na ispitivanje mogućnosti njihove prerade luzenjem sumpornom kiselinom u prisustvu natrijum-nitrata kao oksidansa. U ovom radu je prikazan deo ispitivanja vezan za luženje cinka iz polimetaličnog koncentrata и pomenutim uslovima i obuhvata sledeće termodinamičku analizu mogućih reakcija luženja, karakterizaciju polimetaličnog koncentrata, ispitivanje uticaja temperature i vremena na izluženje cinka i kinetičku analizu eksperimentalnih ispitivanja.",

AB  - The performed investigations were directed toward the analysis of the performance and activity of the fresh and regenerated Cyanamid HDS 20C catalyst in a laboratory batch reactor (2 dm3) for the HDS of the diesel fraction (light gas oil, LGO). Testing of the regenerated catalyst was performed with light gas oil (LGO) of different characteristics. The determined values of the reaction rate constant were compared to some published data in the literature for the HDS of specific sulfur compounds as well as the values of the activation energy. The rates of deactivation of the fresh and regenerated catalyst actually existed compared to some other results recently published in the literature. However, such an observed differences were not sufficient to derive a relation which could be used for the determination of the rate of catalyst deactivation.
AB  - Ispitivanja aktivnosti novog (svežeg) i regenerisanog katalizatora tipa Cyanamid HDS 20C je realizovano u ovom radu u laboratorijskom šaržnom reaktoru (2 dm3). Smanjena aktivnost regenerisanog u odnosu na svež katalizator povezana je promenom izračunate konstante brzine reakcije desulfurizacije lakog gasnog ulja. U cilju određivanja konstante brzine merena je konverzija sumpornih jedinjenja i određivana kinetika procesa HDS primenom integralne metode. Lako gasno ulje različitog porekla (iz nafte Ural REB sa 0,92 mas% sumpora i nafte "Kikinda" sa vojvođanskih izvora sa 0,092 mas%) je korišćeno u ovim ispitivanjima. Određena je konstanta brzine i energija aktivacije procesa HDS pod pretpostavkom da je u pitanju pseudo reakcija I reda. Dobijene brojne vrednosti su upoređene sa objavljenim rezultatima u literaturi koji se odnose na HDS čistih model jedinjenja (tiofen, benzotiofen, dibenzotiofen i supstituisani deri-vati ovih jedinjenja). Utvrđeno je da postoji samo mala razlika u određenoj prividnoj konstanti brzine (tj. i aktivnosti) za svež i regenerisan katalizator na 300°C, koja postaje sve veća kako se proces izvodi na višim temperaturama (350°C). Ovako ponašanje regenerisanog katalizatora može se objasniti činjenicom da LGU u svom sastavu ima pored slabije reaktivnih sumpornih jedinjenja aromatskog tipa (benzo i dibenzotiofeni) i izvestan udeo jedinjenja tipa sulfida, disulfida i tiofena koji su mnogo reaktivniji. Takav odnos manje i više reaktivnih jedinjenja sumpora utiče na ukupan efekat HDS i potrebu da katalizator poseduje potrebnu aktivnost kako bi se tek na višim temperaturama ostvarila željena konverzija sumpornih jedinjenja aromatskog tipa. Ponovljeni eksperimenti pod istim uslovima ukazuju da postoji razlika između brzina deaktivacije svežeg i regenerisanog katalizatora kao i da se brzine deaktivacije može dovesti u vezu sa objavljenim rezultatima iz literature. Međutim, uočeni efekti deaktivacije katalizatora i podaci koji se mogu iskoristiti nisu bili dovoljni da se detaljno prouči i definiše brzina deaktivacije katalizatora.
