The experiments were carried out in sulfuric acid solution and with the addition of Fe(III) ions that had the role of oxidant. During the leaching period of 23 days, with sulfuric acid, the concentration of copper in the solution ranged from 0.05 to 0.230 g/dm3, and iron from 0.125 to 0.350 g/dm3. With the addition of Fe(III) ions to the process, the concentration of copper in the solution moved in the same range. These results show that a longer period is needed for the oxidation and dissolution of this raw material. 2023 Bogdanović, Dejan Marilović, Dragana Nikolić, Bojan Petrović, Sanja Proceedings International Mineral Processing and Recycling Conference (15 ; 2023 ; Belgrade) startpage: 230 endpage: 235 eng info:eu-repo/semantics/conferenceProceedings Keywords: Leaching, Copper, Sulfuric Acid, Fe(III) ions.
