Extracting Zinc Raw Materials

The roasted zinc material is now mostly soluble in acid and is deposited towards the bottom of the roaster. Once cooled and ground, it is then pumped into the reservoir of the leaching plant. The roasted material from the mine is purified along with recycled material called volts oxide. Volts oxide is an important raw material for making Zinc.
