Patent abstract
A method of treatment or purification of a molybdenum concentrate also containing copper, comprises the step of subjecting the molybdenum concentrate to pressure oxidation in the presence of oxygen and a feed solution containing copper (e.g. CuSO4) and halide (e.g. CuCl2) to produce a pressure oxidation solution containing copper and a solid residue containing molybdenum. The pressure oxidation solution may be combined with feed solution to a second pressure oxidation in which a copper concentrate is treated for the recovery of copper therefrom.
