    The ores of zinc are concentrated and roasted in air to produce zinc oxide. The oxide is then mixed with coke and heated to a temperature of about 1300*C in a fireclay retort to give zinc and carbon(II)oxide. The zinc produced distills over as vapour and then condenses into a liquid in a container.
