Forced air flotation cell FLSmidth

Forced air flotation cell FLSmidth

Flotation is about creating the proper energy dissipation rate in the cells to obtain optimal contact between the air bubbles and the particles for extracting the minerals. The function of the rotor/stator is to make bubbles from the forced air, suspend the particles, and create an environment for bubbles and particles to make contact and rise ...

Oct 01, 1995 The principle of this method is that at least one other gas besides the oxidative gas is used in the machine. The selection of the gas mixture is based on the potential level in the pulp which is monitored either by mineral electrodes prepared from the individual ore or by metal electrodes in the case of precious metal flotation.

Froth Flotation and Gold Extraction Manhattan Gold amp Silver

Jul 23, 2014 Froth Flotation and Gold Extraction. Most methods of water-based gold extraction are dependent on gold’s lack of buoyancy to work. However, froth flotation uses a different property of gold to separate it from ore. Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water).
