Mineral processing is the first step for ore once it leaves the mine. The process involves ore preparation, milling, and ore dressing, commonly known as beneficiation. Beneficiation mechanically separates the grains of ore minerals from the gangue (low-value) minerals that surround them in order to produce a concentrate made up of useful minerals.

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.
