Get Price· Solution: Zinc is not extracted from zinc oxide through reduction using CO. Reducing agent should have more negative ΔG value. However in present case, Zn has more negative ΔG value then CO, so it can not be reduced by CO.
Get Price· At the furnace temperatures zinc exists in vapour form, and leaves at the top of the furnace. Liquid zinc being lighter settles above molten lead and is run off; The vapour is condensed in a spray of molten lead to prevent reoxidation of zinc. The resultant zinc is 9899% pure and can be further purified by distillation.
