| 摘要 |
The invention relates to a hydrometallurgical process for the treatment of polymetallic minerals and sulphur concentrates of copper and zinc, and by-products from lead smelting plants and zinc plants, treated independently and/or as mixtures with relevant contents of lead, copper, zinc, iron, gold and silver, such as the matte-speiss mixture from lead smelting plants, and copper cements from the purification processes of electrolytic zinc plants. The process allows the recovery of the metals copper and zinc, copper in the form of the basic salts thereof, and zinc, that can be hydroxides, carbonates, hydroxysulphates or mixtures thereof; the production of stable arseniferous wastes; and the effective and efficient recovery of Pb, Au and Ag as a concentrate of lead sulphide and/or lead sulphate Au and Ag. |
