The mineral is usually transferred to the froth leaving behind the gangue in the pulp. This is termed as direct flotation. However, during reverse flotation the gangue is separated into the float fraction while the valuable mineral is retained in the pulp. The process can only be applied to relatively fine particles.

In broader terms, mineral processing consists of two functions. Firstly, it involves the preparation and liberation, of the valuable minerals from waste minerals and secondly, the separation these values into two or more products, called concentrates. The term separation in this case is synonymous with concentration.
