Abstract

FIELD: hydrometallurgy of nonferrous metals. SUBSTANCE: cobalt concentrate containing trivalent cobalt is treated in metal chloride solution and pulp is treated at redox value 0.9 (not above) in the presence of reducing agent that is added at excess with respect to reactive chlorine. Concentrate is treated in metal chloride solution taken from the group involving nickel, cobalt, magnesium, calcium, aluminium. Solution obtained after pulp treatment with hydrochloric acid can be used as metal chloride solution also. Reducing agent - metal taken from the group involving nickel, cobalt, iron, aluminium or alloy containing one or more these metals. EFFECT: improved method and ecology. 4 cl, 1 tbl

Claims (4)

1. Способ вскрытия кобальтового концентрата, включающий распульповывание концентрата, содержащего кобальт в трехвалентном состоянии, обработку пульпы соляной кислотой и отделение кобальтсодержащего раствора от нерастворимого остатка, отличающийся тем, что распульповывание концентрата ведут в раствор хлорида металла, а обработку пульпы осуществляют при величине окислительно-восстановительного потенциала не более 0,9 В в присутствии восстановителя, который вводят с избытком по отношению к реакционному хлору.1.
