o:4123 Hydrometallurgical treatment of mining waste from Bor - Serbia in aim of copper recovery en Abstract: Flotation tailings deposited on the Old Flotation Tailing Dump in Bor contains 0.2-0.4% Cu and represents a significant resource for recovery of copper and other useful components. The results of experimental laboratory tests of the copper recovery process from the flotation tailings using the beaker leaching (BL) and high pressure leaching (HPL) are given in this paper. By the use of beaker leaching, the degree of copper recovery of 70% and iron of 12% at temperature of 60°C, time of 24 hours and concentration of sulfuric acid of 15 g/l was achieved. A high degree of copper recovery of 99% was achieved by the high pressure leaching using water as an leaching reagent at a temperature of 180°C and pressure of 1.5 MPa. Keywords: flotation tailings, beaker leaching, high pressure leaching, copper recovery. 91552100 134552073 1552100 978-86-6305-140-9 2024-03-05T17:21:50.298Z 44 no 46 Ljiljana Avramović Institut za rudarstvo i metalurgiju Bor 23392871 0000-0002-3747-1530 2023 46 Zoran Stevanović Institut za rudarstvo i metalurgiju Bor 9619303 0000-0001-5317-6884 2023 46 Vanja Trifunović Institut za rudarstvo i metalurgiju Bor 84760329 0000-0003-4839-8751 2023 46 Radmila Marković Institut za rudarstvo i metalurgiju Bor 67811081 0000-0001-9754-1150 2023 46 Dragana Božić Institut za rudarstvo i metalurgiju Bor 52519945 0000-0003-1055-8449 2023 46 Daniela Urošević Institut za rudarstvo i metalurgiju Bor 10370663 0000-0003-3490-7834 2023 46 Silvana Dimitrijević Institut za rudarstvo i metalurgiju Bor 25647975 0000-0003-1670-4275 2023 application/pdf 1917659 https://unilib.phaidrabg.rs/o:4123 no yes 1 70 669 92000004 71A03 Proceedings International October Conference on Mining and Metallurgy (54 ; 2023 ; Borsko jezero) 128 131 2023
