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.

Zinc ore occurs in two types of deposit as primary zinc ore in thin veins known as rakes or a secondary deposit formed by weathering of the primary mineral veins Zinc ore is most commonly found as zinc carbonate (ZnCO 3) known as calamine or smithsonite It generally occurs as rounded crystalline crusts or granular honeycombed masses that.
