Manufacturing Process
High-purity copper scrap or copper oxide is dissolved in sulphuric acid under controlled conditions. The resulting solution is purified, filtered and crystallised to obtain Copper Sulfate Pentahydrate crystals, which are then dried, screened and packed. Each lot is tested for assay, copper content, insoluble matter and heavy metals.
