Измельчение халькопиритных концентратов как метод интенсификации процесса выщелачивания

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 con-centrates using oxidative autoclave leaching at different temperature parameters. In this paper, method of leaching process intensifying through preliminary grinding the material to a size of 90% of the class - 13 μm is presented.
