METHOD FOR ENRICHMENT OF METALLIFEROUS SCUM AND SLAG Russian patent published in 2017 - IPC C22B7/00 C22B11/00 B03D1/18 C22B3/04

Abstract RU 2617192 C1

FIELD: metallurgy.

SUBSTANCE: scum and slags are processed with microwave energy for 1-10 minutes, powdered, large particles of metal are extracted by gravitational methods, and gravitation rejects are subjected to flotation with xanthate and aerofloat used as collectors at pH=8÷9, then at pH=3.5÷5. Sodium dialkyldithiophosphate is used as an aerofloat at a rate of 50÷500 g/t.

EFFECT: increase degree of precious metals and copper extraction.
