electrowinning for copper in china

1) Leaching of roasted zinc concentrates in dilute sulfuric acid, i.e., ZnO + H2so4 = znso4 + H2. o. 2) Purification of the resulting zinc sulfate solution. 3) Electrolysis to recover the metallic zinc as a high purity product. Only the high hydrogen overvoltage on zinc permits the deposition of zinc at the cathode since thermodynandcs

The filtrate is pro- cessed in a zinc cementation tank to pre- cipitate metals more electronegative than zinc (e.g., lead, cadmium) and then pumped to a zinc electrowinning system. The non- zinc sludge waste from the digester (pri- marily copper and nickel) is digested with suffuric acid and filtered to produce a resi- due containing precious ...

Copper Electrowinning Plant China

Zinc is extracted from the purified zinc sulfate solution by electrowinning, which is a specialized form of electrolysis. The process works by passing an electric current through the solution in a series of cells. This causes the zinc to deposit on the cathodes (aluminium sheets) and oxygen to form at the anodes.
