dc.description.abstractThis paper aims to consider the treatment of jarosite residue using a different reducing agents, aluminum, magnesium, and carbon. The jarosite residue is not standard-it contains higher amounts of Pb and Ag, as well as in, Ga and Ge. We show thermodynamical conditions of gas phase equilibrium for the given experiments and predominance diagrams that show potential for obtaining critical metals in the metallic phase. Using a mixture of aluminum and magnesium, as reducing agents, showed proper fuming of Zn and Pb at a temperature of 1200 °C. However, magnesium alone, and carbon in the mixture of reducing agents cause poor results for zinc fuming, which is explained by the modeling of the given compositions.en
dc.description.abstractU ovom radu prikazan je metod tretmana jarosit ostatka pomoću različitih reducenata: aluminijuma, magnezijum i ugljenika. Jarosit ostatak nije standardan -sadrži veće koilčine Pb i Ag, a pored njih i in, Ga i Ge. Prikazani su termodinamički uslovi ravnoteže gasne faze za date eksperimente, kao i uslovi u kojima će kritični metali biti sakupljeni u metalnoj fazi. Korišćenjem mešavine aluminijuma i magnezijuma kao reducenata postignuto je dobro isparavanje Zn i Pb na temperaturi od 1200 °C. Međutim, korišćenje samo magnezijuma ili ugljenika sa ostalim reducentima dovode do lošijih rezultata isparavanja cinka, što je objašnjeno modelovanjem datih sastava iz eksperimenata.sr
