Extraction of Zinc Application Of Zinc Refining Process

Themonly 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. Due to its very low boiling point, at such temperatures, zinc will escape with exhaust gases.
