Flotation machines consist of several key components, including: Tank: The tank is the vessel where the flotation process takes place. It is typically made of steel and is designed to withstand the pressure and wear and tear of the flotation process. The tank is often divided into several compartments to allow for multiple stages of flotation.

The idea of selective flotation is to "concentrate" and put as much metal in as little a concentrate mass as possible. Pulling more mass has complicated process and mechanical implications as larger mass often cannot be handled by pumps or flotation cells for lack of volumes.

Mechanical flotation cells can be broken down into two broad categories based on how air is introduced to the cell. In a self aspirated flotation cell air is introduced to the slurry, the vacuum created by the rotorusing . In a forced air flotation cell air is generated external to the cell by a low pressure blower,, and pumped down the
