Abstract


Ural enrichment plants processing copper-porphyry deposits are obtained concentrates of the following chemical composition, %: 21.5 Cu, 0.1 Zn, 26.59 S, 24.52 Fe, 0.05 Pb, 0.04 Ni, 16.28 SiO2 [1]. Previous studies [2,3] confirmed the possibility of processing such concentrates using oxidative pressure leaching at different temperature parameters. The leaching residue contain the following compounds, %: 55 Fe2O3, 40 SiO2, 4 MeS2 / MeS. This paper present the results on purification of leaching residues from iron, and the preparation of monosyllables
