FIELD: metallurgy.
SUBSTANCE: invention refers to hydro-metallurgy, particularly to procedure of processing silicate cobalt-nickel ore for extraction of valuable components. The procedure consists in leaching ore in acid medium with pH in the interval 1.5-2.15 at temperature 20-23°C. Also leaching is performed with solution with autotrophic bacterial cultures, where amount of micro-organisms in solution equals to 105-107 cl/ml. Leaching is carried out at continuous aeration, normal atmospheric pressure and periodic replacement of solution.
EFFECT: raised level of extraction of valuable components, reduced power expenditures.
