Zinc: smelting, producing and classification .

Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. The most common zinc concentrate processed is zinc sulfide, which is obtained by concentrating sphalerite using the froth flotation method.There are two methods of smelting zinc: the pyrometallurgical process and the hydrometallurgical process (over 90% of hydrometallurgical process is in

Lead smelting Wikipedia

Plants for the production of lead are generally referred to as lead smelters.Primary lead production begins with sintering.Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will combine with those oxidizing elements to free the metal.
