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 14):
A hydrometallurgical method as defined in  claim 1 , wherein the first compartment of the multi-compartment autoclave is preferably divided from the other compartments by a divider construction that restricts the free flow of the autoclave vapour phase from the first compartment to other compartments, i.e. the divider construction forms the division between the first compartment and the second and ensuing compartments so that the transfer of unused oxidant gas from the first compartment to the second and ensuing compartments is minimised or not permitted.
