o:5962 Correlation of Fe2+ with Cu2+ and Zn2+ in the bioleaching process en Abstract: This paper describes the impact of adding pyrite and ferrous sulfate on the recovery of Cu and Zn in the bioleaching process of treating the polymetallic raw materials. For a period of 20 days, at temperature of 300C, phase ratio S:L=1:5 and pH=2 with bacterial culture At. Ferrooxidans and At. Thiooxidans, higher Cu leaching was achieved with addition of pyrite compared to the addition of ferrous sulfate, and significantly lower leaching of Zn for both cases of addition pyrite and ferrous sulfate. Keywords: bioleaching, polymetallic ore, metals recovery, pyrite, ferrous-sulphate. 91552100 138193673 1552100 978-86-7827-052-9 2024-11-02T13:53:15.843Z 44 no 46 Vesna Conić Institut za rudarstvo i metalurgiju Bor 55525641 0000-0002-4268-3626 2022 46 Suzana Dragulović Institut za rudarstvo i metalurgiju Bor 77776905 0000-0001-5086-5115 2022 46 Dragana Božić Institut za rudarstvo i metalurgiju Bor 52519945 0000-0003-1055-8449 2022 46 Dragan Milanović Institut za rudarstvo i metalurgiju Bor 6197863 2022 46 Ivana Jovanović Institut za rudarstvo i metalurgiju Bor 79412745 0000-0002-7450-6632 2022 46 Srđan Stanković Federal Institute for Geosciences and Natural Resources, Hannover, Germany 14140519 0000-0002-2034-456X 2022 46 Jelena Avdalović Institut za hemiju, tehnologiju i metalurgiju, Univerzitet u Beogradu 23432551 0000-0001-9917-7997 2022 application/pdf 294259 https://unilib.phaidrabg.rs/o:5962 no yes 1 70 669:622.7 92000004 71A03 Proceedings International October Conference on Mining and Metallurgy (53 ; 2022 ; Bor) 195 198 2022
