FIELD: metallurgy.
SUBSTANCE: invention refers to concentration of minerals and can be implemented at processing sulphide poly-metallic ore. The procedure consists in ore crumbling in soda medium at presence of xanthate and in successive collected flotation of sulphides of copper, lead and zinc using xanthate and foaming agent. Natural non-organic sorbent on base of opal-cristobalite (siliceous) rock referred to a casting box group is additionally introduced during operation of ore crumbling before flotation.
EFFECT: raised efficiency of flotation.
