The process of froth flotation involves crushing and grinding the ore to a fine size This separates the individual mineral particles from the waste rock and other mineral particles. The grinding is normally done in water with the resultant slurrycalled the pulp. The pulp is processed in the flotation cells.

Mineral Processing. If the mineralogy of the ore shows that you can separate discrete particles of the mineral you want from theponents of the ore, then it is possible to physically concentrate the valuable mineral and reject the rest. The easiest method for achieving this is by gravity separation.
