    Control of an industrial copper solvent extraction process
    The aim of the copper solvent extraction process is to concentrate aqueous copper solution from a few g/l to about 40 50 g/l and to purify the solution from ferrous, manganese, chloride and other impurities, which are harmful for the downstream electrowinning process. This continuous process consists of extraction and stripping processes,
