how to process zinc from its ore
Extraction of
During this process, zinc oxide is obtained from the zinc sulfide ore. The equation for this process is: 2 ZnS + 3 O2 → 2 ZnO + 2 SO2 Small amount of ZnS may be oxidized to ZnSO 4 but above 900 0 c, ZnSO 4 decompose forming Zinc Oxide (ZnO) ZnS + 2O 2 → ZnSO 4 ZnSO 4 above 900 → 2ZnO + 2SO 2 + O 2 (c) Process of smelting (reduction) Here, the mixture of .

Zinc production environmental impact
Zinc occurs only in a combined state. The dominant zinc ores found in the earth's crust is zinc blende (zinc sulphide or spharelite) ZnS, calamine ZnCO3 and Zincite, Zno. Zinc is commonly found in mineral deposits along with other base metals, such as copper and lead. Zinc deposits are broadly classified on the basis of how they are formed.

Global zinc production is primarily from its ore, zinc sulphide, commonly known as sphalerite. Almost half of all the zinc produced is used for galvanisation; the process of coating iron or steel with a thin layer of zinc to protect it from corrosion. This process can drastically increase the recyclability of steel and iron.
