Class 12 Chemistry Isolation of Elements Extraction of Zinc from Zinc Oxide

Extraction of Zinc from Zinc Oxide

  • The reduction of zinc oxide is done using coke. The temperature in this case is higher than that in case of copper.
  • For the purpose of heating, the oxide is made into brickettes with coke and clay.
    • ZnO + C àZn + CO (where coke is the catalyst, and temperature is 673 K)
  • The metal is distilled off and collected by rapid chilling.
