Froth flotation - wikidoc

Froth flotation commences by comminution (that is, crushing/grinding), which is used to increase the surface area of the ore for subsequent processing and break the rocks into the desired mineral and gangue, which then has to be separated from the desired mineral. The ore is ground into a fine powder.
