Abstract
Leaching of attritor-ground chalcopyrite concentrate by acidified ferric sulfate, generatedin situ, has been studied. Air and oxygen alone and mixed with sulfur dioxide were tested as oxidizing agents. A specially designed reactor, which allowedn situ oxidation of ferrous sulfate, permitted the leaching of a 20 pct solids slurry with high copper recovery. The leachate contained ~ 53 g/l copper, a high enough concentration that solvent extraction may not be necessary.
