Extraction of Zinc Appli ion Of Zinc Refining Process

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. Zinc Blende does not contain a very high percentage of zinc and hence it needs to be concentrated. The best concentration method for zinc ore is known as froth flotation.
