METHOD FOR SILVER FLOTATION FROM ACID CAKES OF ZINC PRODUCTION Russian patent published in 2013 - IPC C22B11/00 B03B5/28

Abstract RU 2496892 C1

FIELD: metallurgy.

SUBSTANCE: method for silver flotation from acid cakes of zinc production involves introduction of a collecting agent - butyl xantate and a foaming agent - flotation oil to a flotation pulp of cakes. Prior to introduction of butyl xantate and flotation oil, pulp is subject to conditioning with tetrachloroethylene supplied in the form of water emulsion that has passed ultrasonic treatment.

EFFECT: increasing silver content in concentrate, which is achieved owing to removing elemental sulphur from mineral surface.
