Najpre je uzorak homogenizovan, a zatim je urađena granulometrijska, XRD i hemijska analiza uzorka jarozita. Primenjeni agensi za proces luženja bili su HCl, HNO3, NaCl i H2SO4. Istraživanja su pokazala da je najprihvatljiviji postupak tretmana jarozita luženje jarozita sumpornom kiselinom, pri čemu su dobijena najbolja izluženja Cu, Zn i In i to 93,76%, 91,64 i 97,59% respektivno. Abstract: The paper presents the results of treatment of technogenic raw materials by the leaching process in order to valorize economically valuable metals Cu, Zn and In and minimize the negative impact of leached residue on the environment. First, the sample was homogenized, and then granulometric, XRD and chemical analysis of the jarosite sample was done. The leaching agents used in experiments were HCl, HNO3, NaCl and H2SO4. Investigations have shown that the most acceptable method for the treatment of jarosite is leaching of jarosite using sulfuric acid, where the best leaching of Cu, Zn and In was obtained, namely 93.76%, 91.64 and 97.59%, respectively.
