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 Get price
