matte grade nickel and copper recovery calculations

    Recovery of nickel and copper from high-grade .

    High-grade nickel-copper matte is treated at Impala Platinum to produce nickel briquettes and copper cathodes. The remaining residue is separately treated for the recovery of platinum group metals. The major portion of the nickel values is preferentially extracted in a first stage acid oxidation leach.

    Note: Until I added the questions in July 2015, I had always assumed (on no good evidence - never a good idea!) that chalcopyrite contained copper and iron both in the +2 oxidation state - but that may well be wrong. If it was true, then you can show that the sulphide ions are reducing Cu(II) to Cu(I). However, if the copper was in the +1 state originally, then the sulphide ions are reducing ...

    12.3 Primary Copper Smelting

    Converting the matte yields a high-grade "blister" copper, with 98.5 to 99.5 percent copper. Typically, blister copper is then fire-refined in an anode furnace, cast into "anodes", and sent to an electrolytic refinery for further impurity elimination. Roasting is performed in copper smelters prior to charging reverberatory furnaces. In roasting,

    As you can see in the example above, the deposit does not have to be enormous in size (only 500 meters long by 100 meters wide) to contain a valuable deposit (approximately $6 billion worth of minerals). However, in order to be as realistic as possible about this valuation, you can not assume that the complete ore body contains the same grade (i.e. 2% copper and 1.5 gram per tonne gold).
