Zinc Electrowinning Equipment for Sale

Most metals occur in nature in their oxidized form (ores) and thus must be reduced to their metallic forms. The ore is dissolved following some preprocessing in an aqueous electrolyte or in a molten salt and the resulting solution is electrolyzed. The metal is deposited on the cathode (either in solid or in liquid form), while the anodic reaction is usually oxygen evolution. Several metals are naturally present as metal sulfides; these include copper, lead, molybdenum, cadmium, nickel, silver, cobalt, and zinc. In addition, gold and platinum group metals are associated with sulfidic base metal ores.

The electrowinning of zinc is sensitive to metallic impurities especially from the points of view of current efficiency and purity of the deposit. Moreover, the effect of impurities in combination is in general detrimental to electrolysis than of single impurity. The organci addtion agents are known to influence the nature of deposit and current efficiency.

SBM provides high performance zinc electrowinning equipment for sale. It also can be applied for many other types of metal processing. The most common electrowon metals are lead, copper, gold, silver, zinc, aluminium, chromium, cobalt, manganese, and the rare-earth etc. For aluminium, this is the only production process employed.

Zinc Separation Machine Supplier

Due to low zinc content, run-of-mine zinc-bearing ores must be concentrated before smelting and refining. Beneficiation, which usually occurs at the mine, consists of crushing, grinding, and flotation to produce concentrates of 50 to 60 percent zinc. Lead ore also requires processing to remove rock and mineral impurities to achieve a suitable concentration.

SBM is world famous supplier and manufacturer of crushing, grinding and beneficiation equipment. With know-how technology, we provide complete range of lead and zinc beneficiation equipment for sale, including quarry machine, crushing plant, grinding mill, screening machine, separation machine, processing plant etc.
