    <ns1:description language="sr">Sažetak: U radu su prikazani rezultati tretmana tehnogene sirovine, otpadnog taloga jarozita postupkom
luženja radi valorizacije ekonomski vrednih metala Cu, Zn i In i minimiziranja negativnog uticaja lužnog ostatka
na zivotnu sredinu. 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.</ns1:description>
    <ns1:description language="en">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.</ns1:description>
