RECOVERY OF ZINC FROM ZINC BEARING SULPHIDE MINERALS BY BIOLEACHING AND ELECTROWINNING

摘要

A method of recovering zinc from azinc bearing sulphide mineral slurry which includesthe steps of subjecting the slurry to a bioleachingprocess, supplying a feed gas which contains inexcess of 21% oxygen by volume, to the slurry,and recovering zinc from a bioleach residue of thebioleaching process.
