Abstract:
A hydrometallurgical method  80  for the removal at least one of iron, aluminum, arsenic, sulfur, nickel, cobalt, zinc and cadmium (impurities) from a copper concentrate to produce an upgraded copper concentrate  92,  the method comprising the step of: subjecting the copper concentrate to an acidic leaching process (NONOX leach  120 ) in a multi-compartment autoclave using a copper sulfate containing lixiviant under lowered electrochemical conditions, to implement a controlled removal of between 20% and 99% of at least one of the impurities to produce the upgraded copper concentrate. The NONOX leach  120  is conducted to produce the majority of required soluble copper sulfate from a partial oxidation of the feed copper concentrate in a first compartment  200  of the multi-compartment autoclave under particular conditions.

Claim (Index 4):
A hydrometallurgical method as defined in  claim 1 , wherein the electrochemical potential of the NONOX leach is controlled by the presence of, or the addition to the NONOX leach of, one or more of cupric sulfate, ferric ion, air, oxygen, pyrolusite, or hematite.
