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
