Abstract

A method of extracting metal from sulphide ores, which includes the steps of solubilizing the metal into a sulphate solution, and generating sulphide by anaerobic bacterial action in the sulphate solution, thereby to cause the metal in the solution to be precipitated as an insoluble sulphide, thus upgrading the metal into a highly concentrated form.
