Zinc mining

Zinc mining is the process by which mineral forms of the metal zinc are extracted from the earth through mining.A zinc mine is a mine that produces zinc minerals in ore as its primary product. Common co-products in zinc ores include minerals of lead and silver. Other mines may produce zinc minerals as a by-product of the production of ores containing more valuable minerals or metals, such as Get price

Mining Of Zinc

At first, the zinc ore is crushed in the zinc mining equipment and the zinc ore is miledl after it is moved to the crushing place. The raw material used for the production of zinc is zinc concentrate, which is the result of a flotation process after the ore has been mined and crushed. Get price

Lead and Zinc Smelting

allurgical process, ore concentrate containing lead, zinc, or both is fed, in some cases after sin-tering, into a primary smelter. Lead concentra-tions can be 50–70%, and the sulfur content of sulfidic ores is in the range of 15–20%. Zinc con-centration is in the range of 40–60%, with sulfur content in sulfidic ores in the range of 26–34%. Get price

Skagway Ore Terminal

Lead and zinc ore concentrate from the Yukon was loaded onto freighters and barges at the terminal from 1967-1997, with brief interruptions from 1982-1986 and 1995-1997. An estimated volume of 50,000 tons of low-grade zinc (60%) and lead (40%) ore concentrate from the Faro Mine passed through the terminal each month. Get price

Copper Concentrates

Concentrates are the raw material for all copper smelters, which by processing it obtain an impure form of metallic copper, anode or blister copper, which is later used to produce high purity refined copper.
