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.
