Zinc occurs naturally in air, water and soil, but zinc concentrations are rising unnaturally, due to addition of zinc through human activities. Most zinc is added during industrial activities, such as mining, coal and waste combustion and steel processing.

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 are two methods of smelting zinc: the pyrometallurgical process and the hydrometallurgical process (over 90% of hydrometallurgical process is in ...

Zinc Mining. The most commonly available ore used in the extraction of Zinc is called Zinc Blende also known as Zinc Sulphide (ZnS). Historically extraction of zinc has been more difficult than extraction of other metals because at temperatures where metals such as iron typically begins to melt, zinc is a gas.
