What is an SX/EW plant? Florence Copper

Mar 24, 2016In the electrowinning process, electric current is used to plate out the copper into copper cathodes. (Similar to chrome electroplating on a bumper.) All water used through this process is treated and recycled back into the extraction process. Most of the direct jobs on site will be at the SX/EW facility. Back to the blog index

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,
