how is zinc extracted from its ore? | Yahoo Answers

 · The vapor is collected in a condenser. The following equations demonstrate this process: 2 ZnO + C → 2 Zn + CO2. 2 ZnO + 2 CO → 2 Zn + 2 CO2. Electrowinning processing leaches from the concentrate by sulfuric acid: ZnO + H2SO4 → ZnSO4 + H2O. After this step electrolysis is used to produce metal.

Extracting Lead Materials from Ore

Lead Materials from . Lead is a dense, soft, low-melting metal. Lead is the densest common metal except for gold, and this quality makes it effective in sound barriers and as a shield against X-rays.Lead resists corrosion by water, so it makes a long-lasting roofing material.. Only about half of the lead materials used today are produced from mining, the rest is obtained from ...

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 gold, silver or copper. Mined ore is processed, usually on site, to produce one or more metal-rich concentrates, then tr…
