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.

Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry.
The process of froth flotation entails crushing and grinding the ore to a fine size.Lime is often used to raise the pH of the pulp and also reduce the flotation of iron pyrite.The tailing from the lead flotation circuit is the feed to the zinc circuit.
