Before smelting, zinc sulfide is usually concentrated by a float and sink method. The zinc sulfide is then roasted to form zinc oxide, followed by reduction with carbon and/or carbon monoxide. Zinc metal is distilled off. About half the zinc produced is used as a coating metal. The most common method of coating is hot-dip galvanizing.
