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 16):
A hydrometallurgical method as defined in  claim 1 , further comprising feeding into the NONOX leach a copper sulfate slurry from a crystalliser or a copper sulfate leach liquor from an external pressure oxidation reactor (PROX reactor), or copper sulfate solution from an external source, or a copper sulfate leach slurry direct from a PROX reactor.
