The flotation process for the concentration of ores is a method by means of which one or more of the minerals in the ore (usually the valuable ones) are picked up by means of a liquid film and floated at the surface of a mass of fluid pulp. Here they are separated from the other minerals, which remain immersed in the body of the pulp. In …

Dissolved Air Flotation works on the principle of letting air, dissolved in water under pressure, form micro bubbles (10-50 micron) at the bottom of a tank. The microbubbles rise up to the surface, and as they form and grow, the bubbles take oil, greases, and small solids with them. The physics of this process are described below.
