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  - This paper presents the experimental investigation results of the polymetallic copper concentrate oxidation process with the oxygen from the air. Concentrate characterization included chemical analysis, X-ray diffraction (XRD), energy dispersive X-ray fluorescence (EDXRF), and light microscopy. Chemical analysis and EDXRF results showed that the investigated copper concentrate consisted mainly of copper, iron and sulphur, with small amounts of zinc, lead, arsenic and other minor elements. XRD analysis showed that metals were bonded to sulphur in sulphide minerals: chalcopyrite, pyrite, luzonite, sphalerite and enargite. Those minerals were mutually bonded into aggregates, confirmed by light microscopy. The results of DTA/TG analysis were used for determining the mechanism of the oxidation process. Comparison between experimental data obtained by XRD, DTA/TG and data obtained from the phase stability diagrams, implied that the oxidation process of the investigated concentrate can be divided in two stages: the first stage consisted of sulphide oxidation reactions with the characteristic exothermal effects below 973 K while forming sulphates and oxysulphates, and the second stage, which consisted of sulphates and oxysulphates decomposition reactions and forming copper and iron oxides, with endothermal effects above 973 K. Kinetic studies were carried out in isothermal conditions in the temperature range (573-873) K. Calculations were done according to Sharp's method of reduced half-time reaction. Calculated values for the activation energies were 82 kJ mol(-1) for the initial stage of the oxidation process (up to 723 K), and 42 kJ mol(-1) for the stage of the process where desulphurization degree reached 68-86 % for the oxidation temperatures 748 K and higher. Calculated activation energy values indicated that the reaction of oxidation is a chemically controlled reaction.

AB  - An electrochemical investigation was conducted to evaluate the corrosion behavior of iron in deionized water (DIW) and medium salt in the pH range of 1 to 4. The times of immersion of the electrode in solutions were changed in the range of 0 to 120 hours. Corrosion currents were determined using the linear polarization technique. Tafel slopes, b(a) and b(c) were also determined by Tafel polarization measurements. The effect of Thiobacillus ferrooxidans on the iron corrosion behavior was noticed in both solutions at pH=1. However, a significant difference between DIW and medium salt existed. While in DIW the corrosion increased continuously with time (after first 24 hours) in medium salt it started to increase after five hours, showing the loss of inhibition properties of a protective layer. The increase in current in the presence of bacteria at pH of 1 was noticed: from 205 nA to 320 nA, and from 175 nA to 400 nA, for DIW and medium salt, respectively.

Tehnologija pirometalurškog tretmana koncentrata bakra po konvencionalnom postupku, koja se još uvek koristi u pogonima Topionice u Boru, dovela je do značajne degradacije stanja životne sredine u Boru i okolini. Smanjenje koncentracije bakra u domaćim rudnim ležištima dovela je do neophodnosti prerade rude sa oboda već eksploatisanih rudnih tela u kojima je povećana koncentracija štetnih primesa i pratioca bakra, u prvom redu: Zn, Pb, As, Cd, Hg, Ni, i drugih. U regionu Bora i okoline, ova problematika postaje sve značajnija sa stanovišta buduće ekstrakcije bakra iz domaćih koncentrata. Naime, u pojedinim, još uvek neeksplatisanim, rudnim nalazištima u okolini Bora se nalazi velika količina bakra, ali sa povišenim sadržajem štetnih komponenti.
AB  - Recently, the problems relating to the industrial pollution have become more intensive and important at local as well as global level. The primary reason is an emission of polluting substances that appear as a consequence of various industrial activities. These activities produce the whole range of harms to the environment such as: water pollution, air pollution, hazardous waste production etc. The scope of emission of pollutants and industrial affect on the environment depend on specific characteristics of various industries. Pyrometallurgical treatment of copper concentrates, a conventional technological process, still used in the Copper Smelter in Bor, caused serious damages in the environment (in Bor as well in the region). In addition, the decrease of a copper content in domestic row minerals led to the necessity of treatment ores from the periphery (already exploited mineral ores) with an increased concentrations of harm components and metals tied to copper; first of all, Zn, Pb, As, Cd, Hg, Ni and others. In the Bor region this problem has become more important in regard to the future extraction of concentrates from domestic sources. Namely, in some copper minerals, recently discovered and, hence, not exploited, a significant amount of copper with higher contents of pollutants is present.

AB  - Konvencionalni pirometalurški postupak za dobijanje bakra obuhvata sledeće faze: prženje koncentrata bakra, topljenje nastalog prženca, konvertorovanje bakrenca i plamenu rafinaciju. Anodni bakar se nakon toga podvrgava elektrolitičkoj rafinaciji, pri čemu se dobija elektrolitički bakar. Sadržaj bakra u koncentratima se kreće u vrlo širokim granicama (10-40%), a to zavisi od hemijskog i mineraloškog sastava rude. Pored minerala bakra, u koncentratima su prisutni i sulfidi olova, cinka, nikla, žive, arsena, kadmijuma i antimona, minerali jalovine, kao i retki i plemeniti metali. U procesu pirometalurške prerade koncentrata bakra, prisutne primese, od kojih su neke toksične, raspodeljuju se između nastalih međuprodukata i krajnjih produkata. Naročito velike poteškoće, pri preradi koncentrata, predstavljaju isparljiva jedinjenja, koja prelaze u gasovito stanje i odlaze sa gasnom smešom u atmosferu.

abstract = "Konvencionalni pirometalurški postupak za dobijanje bakra obuhvata sledeće faze: prženje koncentrata bakra, topljenje nastalog prženca, konvertorovanje bakrenca i plamenu rafinaciju. Anodni bakar se nakon toga podvrgava elektrolitičkoj rafinaciji, pri čemu se dobija elektrolitički bakar. Sadržaj bakra u koncentratima se kreće u vrlo širokim granicama (10-40%), a to zavisi od hemijskog i mineraloškog sastava rude. Pored minerala bakra, u koncentratima su prisutni i sulfidi olova, cinka, nikla, žive, arsena, kadmijuma i antimona, minerali jalovine, kao i retki i plemeniti metali. U procesu pirometalurške prerade koncentrata bakra, prisutne primese, od kojih su neke toksične, raspodeljuju se između nastalih međuprodukata i krajnjih produkata. Naročito velike poteškoće, pri preradi koncentrata, predstavljaju isparljiva jedinjenja, koja prelaze u gasovito stanje i odlaze sa gasnom smešom u atmosferu. U radu su prikazani rezultati uticaja pojedinih prisutnih komponenti iz koncentrata bakra, na promene koje se odvijaju u životnoj sredini, što za posledicu, između ostalog ima i narušavanje, pa i gubljenje biološkog diverziteta. ., Pyrometallurgical conventional procedure for obtaining copper includes the following phases: copper concentrate roasting, melting, converting and anode refining.
