The primary ore is galena or Lead sulphite PbS. This is unstable, and on prolonged exposure to the atmosphere it oxidizes into the minerals cerussite PbCO3 and anglesite PbSO4. Lead ores are usually associated with other metals, particularly silver which can be mined at the same time – and zinc, which can cause problems during smelting.

Zinc is mined from many different ores including galena, sulfide and silicate. Usually, the extraction process consists of concentration and roasting of the ore, after which it is reduced to zinc by electrolysis or by heating with carbon. Among the major zinc mining countries in the world are Russia, China, Australia and Peru.

SAM Company has much experience in mining process, almost common metal ores in our comapny can be processed for crushing, grinding, sreening, washing and the .

Zinc ores typically may contain from 3 to 11 percent zinc, along with cadmium, copper, lead, silver, and iron. Beneficiation, or the concentration of the zinc in the recovered ore, is accomplished at or near the mine by crushing, grinding, and flotation process. Once concentrated, the zinc ore is

The process has four stages: a) concentration of the ore b) roasting of the ore in air c) conversion of zinc oxide to zinc sulfate d) electrolysis of zinc sulfate solution (a) Concentration of the ore. The ore is mined, crushed, ball-milled and then concentrated by froth flotation.

The Red Dog facility has been mining and milling lead/zinc ore since late 1989. The ore the mine processes contains lead (5-10%) and zinc (20-25%). Zinc concentrate from the mill contains approximately 56% zinc and 3% lead, while lead concentrate from the mill contains approximately 55% lead and 12% zinc.
