o:5956 Column leaching of low-grade copper sulfide ore with sulfuric acid en Abstract: The paper presents the results of leaching of low-grade copper sulfide ore with average Cu content of 0.33% and an oxide content of about 7%. 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. Keywords: Leaching, Copper, Sulfuric Acid, Fe(III) ions. 91552100 138148105 1552100 978-86-6305-133-1 2024-11-02T11:33:52.086Z 44 no 46 Dejan Bogdanović Tehnički fakultet u Boru, Univerzitet u Beogradu 14596455 0000-0002-4871-4366 2022 46 Dragana Marilović Tehnički fakultet u Boru, Univerzitet u Beogradu 55478281 0000-0001-8301-750X 2022 46 Bojan Nikolić Jiuzhou International Construction doo Bor, Bor 110618633 2022 46 Sanja Petrović Institut za rudarstvo i metalurgiju Bor 60041481 0000-0001-5197-1614 2022 application/pdf 1719326 https://unilib.phaidrabg.rs/o:5956 no yes 1 70 669.333.7.061.34 92000004 71A03 Proceedings International Mineral Processing and Recycling Conference (15 ; 2023 ; Belgrade) 230 235 2023
