How to extract zinc metal from its mineral? | Yahoo Answers

Sep 08, 2011· 2 ZnO + C → 2 Zn + CO2. 2 ZnO + 2 CO → 2 Zn + 2 CO2. Electrowinning processing leaches zinc from the ore concentrate by sulfuric acid:[82] ZnO + H2SO4 → ZnSO4 + H2O. After this step electrolysis is used to produce zinc metal. 2 ZnSO4 + 2 H2O → 2 Zn + 2 H2SO4 + O2. The sulfuric acid regenerated is recycled to the leaching step.
