Abstract

Process for winning metals from sulphuretted prods e.g. mixed sulphide concns, pyritic Cu or Zn-bearing ores, partic chalcopyrite, blends or other similar sulphides, finely dispersed in a mass of iron pyrites comprises (a) treating the milled prodn. in as aq. medium using iron powder in the presence of H2SO4, opt. (b) oxidation using ferric sulphate to put into soln the metals whose sulphate form is water soluble and (c) recovering the metals from the sulphates by known methods. Allows extraction of Cu and Zn without affecting the iron sulphide.
