AB  - Dizajn modernih industrijskih proizvoda je takav da oni predstavljaju kompleksne spojeve različitih materijala. Zbog toga se u postupku reciklaže materijala primenjuju procesi usitnjavanja i razdvajanja. Međutim materijali se ne mogu u potpunosti razdvojiti i zbog toga dolazi do kontaminacija u reciklažnim tokovima. Zbog toga se kvalitet materijala može smanjivati u svakom narednom reciklažnom koraku. Ovakvi kvalitativni gubici ne mogu se opisati masenim bilansom, i u radu je prikazan eksergijski koncept kao merilo gubitaka kvaliteta, odnosno dat je metod za izračunavanje eksergijskog sadržaja i eksergijskog gubitka. 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. U radu je dat primer proračuna na čeličnom otpadu.
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  - 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.

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.

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  - 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.

U radu su proračuni eksergijskih gubitaka tokom reciklaže prikazani na primeru aluminijumskog otpada., 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  - The thermodynamic properties and the microstructure, hardness and electrical conductivity of shape memory alloys (SMAs) belonging to ternary Cu-Al-Zn system were studied by Muggianu model and experiment, respectively. The isothermal section of phase diagram at 293 K was calculated using Thermo-Calc software. Experiments were conducted by X-ray diffraction, light optic microscopy, scanning electron microscopy with energy dispersive X-ray spectrometry, hardness and electrical conductivity measurements. The calculated values of thermodynamic properties indicate that Cu shows good miscibility with Al and Zn in all investigated alloys. The microstructural analysis of samples reveals that the structure consists of large and polygonal grains.

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.

Kao potvrda predloženom mehanizmu, u radu su prezentovani rezultati EDXRF analize polaznog uzorka, XRD analize polaznog uzorka i produkata oksidacije na 550 i 950°C i rezultati SEM/EDS analize polaznog uzorka i produkata oksidacije na 675 °C. Upoređivanjem eksperimentalnih rezultata dobijenih XRD i DTA/TG analizom može se zaključiti da se proces oksidacije ispitivanog koncentrata može podeliti u dva stupnja: prvi stupanj čine reakcije oksidacije sulfida sa karakterističnim egzotermnim efektima ispod 650 °C, dok obrazovanje sulfata i oksisulfata i njihovo razlaganje do oksida bakra i železa čini drugi stupanj, praćen karakterističnim endotermnim efektima na višim temperaturama. Kinetička analiza procesa oksidacije ispitivanog koncentrata izvršena je po metodama Kissingera i Ozawe u neizotermskim uslovima.

AB  - U prikazanom radu ispitivana je selektivna ekstrakcija arsena iz kompleksnog koncentrata na bazi enargita iz rudnika bakra u Boru, korišćenjem Na-hipohlorita kao agensa za luženje. Osnovni cilj istraživanja sastojao se u utvrđivanju uticajnih parametara i njihovog međusobnog odnosa kako bi se ostvarilo maksimalno uklanjanje arsena iz ispitivanog koncentrata. Enargit (Cu3AsS4) spada u rasprostranjene kontaminante koncentrata bakra. Tokom procesa prženja i topljenja arsen obrazuje lako isparljiva jedinjenja koja vrlo negativno utiču na zagađenje ljudi, radne i životne sredine. Zakonska regulativa ne dozvoljava topionicama bakra da tope koncentrate sa više od 0,5% arsena. Za dobijanje optimalnih uslova procesa uklanjanja arsena iz kompleksnog koncentrata bakra na bazi enargita, korišćena je tehnika matematičkog modelovanja. Modelovanje je izvršeno primenom faktorskog dizajna na eksperimentalno dobijene podatke. Odabrano je pet karakterističnih parametara procesa - ulaznih varijabli, za koje se pretpostavlja da imaju uticaja na stepen ekstrakcije arsena: koncentracija rastvora hipohlorita, masa uzorka (koncentrata), brzina mešanja, temperatura luženja i vreme luženja. Faktorski (2n) dizajn zahtevao je izvođenje 16 eksperimenata sa šest replikanata. Nakon izvođenja 22 eksperimenta, rezultati ekstrakcije arsena uzeti su kao izlazna varijabla. Proračunom su dobijene jednačine modela prvog i drugog reda. Koeficijenti u modelu drugog reda ukazuju da temperatura luženja ima najveći uticaj na ekstrakciju arsena. Drugi faktor po značaju je vreme luženja. Pozitivni predznaci ispred ova dva najuticajnija parametra ukazuju da povećanje temperature luženja, odnosno vremena luženja, utiču na povećanje stepena uklanjanja arsena iz ispitivanog koncentrata. Najveća pozitivna interakcija zapažena je između koncentracije hipohlorita i brzine mešanja tokom procesa ekstrakcije. Proračun RMSE (root mean square error) pokazao je dobro slaganje između vrednosti dobijenih eksperimentalnim istraživanjem i vrednosti dobijene modelovanjem. Pouzdanost finalnog modela testirana je primenom ANOVA testa.
AB  - Selective arsenic extraction from enargite based complex concentrate from Copper Mine in Bor (Serbia), using sodium hypochlorite as a leaching agent, was investigated in this paper. The aim was to assess the optimal conditions for the most efficient arsenic removal from the investigated concentrate, based on factorial design applied to experimentally obtained data. Five important factors with three factor levels were used as the input variables and experimentally obtained arsenic extraction yield was taken as the output variable. The first and the second final order model equations were obtained. It was found that the leaching temperature had the strongest effect on the arsenic extraction. The strongest positive interaction was between the sodium hypochlorite molar concentration and the stirring speed during extraction.

AB  - Postupci prerade sekundarnih sirovina bakra uključuju dva osnovna stupnja: pripremu bakarnih otpadaka i njihovu dalju metaluršku preradu. Za pripremu bakarnih otpadaka koriste se različiti postupci u zavisnosti od vrste i kvaliteta sekundarne sirovine. Sve operacije pripreme utiču na kvalitet metalurške prerade, odnosno na kvalitet proizvoda. Za topljenje pripremljenih sekundarnih sirovina u cilju dobijanja legura na bazi bakra koriste se razni agregati: šahtne peći, konvertori, plamene lončaste i koritaste plamene peći, kratke bubnjaste peći i električne peći (elektrolučne, elektrootporne, indukcione).
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. All operations of pretreatment are influencing the quality of metallurgical processing. For metallurgical processing of raw materials prepared for the purpose of obtaining copper and copper alloys the shaft, flaming and short-drum furnaces, converters and electric furnaces (electric resistant, electric arc and induction furnaces) are used.

abstract = "Postupci prerade sekundarnih sirovina bakra uključuju dva osnovna stupnja: pripremu bakarnih otpadaka i njihovu dalju metaluršku preradu. Za pripremu bakarnih otpadaka koriste se različiti postupci u zavisnosti od vrste i kvaliteta sekundarne sirovine. Sve operacije pripreme utiču na kvalitet metalurške prerade, odnosno na kvalitet proizvoda. Za topljenje pripremljenih sekundarnih sirovina u cilju dobijanja legura na bazi bakra koriste se razni agregati: šahtne peći, konvertori, plamene lončaste i koritaste plamene peći, kratke bubnjaste peći i električne peći (elektrolučne, elektrootporne, indukcione)., 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. All operations of pretreatment are influencing the quality of metallurgical processing. For metallurgical processing of raw materials prepared for the purpose of obtaining copper and copper alloys the shaft, flaming and short-drum furnaces, converters and electric furnaces (electric resistant, electric arc and induction furnaces) are used.",

AB  - Nanotehnologije se smatraju pokretačkom snagom nove industrijske revolucije. Nanonauka je tokom poslednje decenije značajno evoluirala od nauke koja se isključivo razvijala u laboratorijskim uslovima, do njene aplikacije u primenjenim tehnologijama. Trenutno, nanomaterijali se koriste u širokom spektru komercijalnih proizvoda kao što su elektronske komponente, sportska oprema, kreme za sunčanje i u biomedicinske svrhe. Veličina nanočestica omogućava im snažnu interakciju sa biološkim strukturama, tako da nanočestice predstavljaju potencijalni rizik po životnu sredinu i zdravlje ljudi. Nanometar kao veličina takođe predstavlja problem za separaciju, reciklažu i ponovno korišćenje nanočestica. Dakle, proizvodnja nanomaterijala u industrijskim razmerama i njihova primena mogli bi imati značajan uticaj na zdravlje ljudi i životnu sredinu ili stvorili probleme pri reciklaži. Sveobuhvatni termin 'nanotehnologija' nije dovoljno precizan kada se radi o upravljanju rizicima. Procena mogućih rizika zavisi od razmatranja životnog ciklusa materijala koji se proizvodi, a koji uključuje razumevanje procesa i materijala koji se koriste u proizvodnji, verovatne interakcije između proizvoda i pojedinaca ili životne sredine tokom proizvodnje nanomaterijala i njegovog životnog ciklusa, kao i metoda koje se koriste za njihovo konačno odlaganje. Sa stanovišta kontrole rizika, neophodno je identifikovati kritične faze, koje je neophodno detaljno istražiti. Pregled aktuelnih trendova ekoloških rizika i reciklaži nanomaterijala prezentovan je u ovom radu.
AB  - Nanotechnologies are being spoken of as the driving force behind a new industrial revolution. Nanoscience has matured significantly during the last decade as it has transitioned from bench top science to applied technology. Presently, nanomaterials are used in a wide variety of commercial products such as electronic components, sports equipment, sun creams and biomedical applications. The size of nanoparticles allows them to interact strongly with biological structures, so they present potential human and environmental health risk. Nanometer size presents also a problem for separation, recovery, and reuse of the particulate matter. Therefore, industrial-scale manufacturing and use of nanomaterials could have strong impact on human health and the environment or the problematic of nanomaterials recycling. The catch-all term ''nanotechnology' is not sufficiently precise for risk governance and risk management purposes. The estimation of possible risks depends on a consideration of the life cycle of the material being produced, which involves understanding the processes and materials used in manufacture, the likely interactions between the product and individuals or the environment during its manufacture and useful life, and the methods used in its eventual disposal. From a risk-control point of view it will be necessary to systematically identify those critical issues, which should be looked at in more detail. Brief review of actual trends in nanomaterials environmental risks and recycling is given in this paper.

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  - Biomasa, kao obnovljivi izvor energije, može se konvertovati u energiju na tri načina: termalnom konverzijom, hemijskom konverzijom i biohemijskom konverzijom. U ovom radu se razmatra konverzija biomase koja potiče od šumskih resursa, odnosno od drvnih peleta. Rezultati pokazuju da ovaj način konverzije energije može biti značajan izvor termalne energije, posebno u oblastima bogatim šumama, kao što je na primer područje Opštine Majdanpek. Toplota proizvedena iz drvnih peleta mogla bi čak da zameni konvencionalni proces dobijanja toplote zasnovan na sagorevanju goriva kao što je, na primer, ugalj.
AB  - Biomass, as a renewable energy source, can be converted to energy in three ways: thermal conversion, chemical conversion and biochemical conversion. In this paper, we consider conversion of biomass that originates from forest resources - wood pellets. The results have shown that this type of energy conversion can be a significant source of the thermal energy, especially in areas rich in forests, such as the municipality of Majdanpek. Heat produced from the wood pellets could even replace a conventional process of heat production based on the combustion of fuels such as, for instance, coal.

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  - 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.

AB  - Hydrometallurgical processes offer a great potential for treating chalcopyrite ores and concentrates, and it results in increased metal recoveries and reduced air pollution hazards. In recent years interest for application of various reagents in a hydrometallurgical processing of sulphide concentrates has increased. The objective of this work was to examine the leaching of the chalcopyrite concentrate, from "Rudnik" flotation plant, by sodium nitrate in sulphuric acid media. The probabilities of various chemical reactions occurring was based upon literature data, thermodynamic analysis, and the products formed during the leaching process. The influence of various parameters was studied to optimize the conditions and to determine the kinetics of the reaction. An increase in temperature, sulphuric acid and sodium nitrate concentration, and decrease in stirring speed and particle size, enhanced the leaching rate of copper. The experimental data were best fitted by a mixed control kinetic model. An activation energy of 83 kJ/mol was found. Elemental sulphur was formed as the main leaching product and tended to inhibit the leaching rate. The leaching mechanism was confirmed by characterizing the concentrate and the leach residue using XRD and SEM/EDX analysis.
