Froth flotation has been a stalwart in mineral beneficiation for more than 100 years. During this time, and particularly in the past 20-30 years, there have been significant advances in the design and application of mechanical elements for flotation systems, e.g., new mechanisms, launders, larger cell volumes, better pumps, etc.
The Imhoflot G-Cell, a new development in the pneumatic flotation technology (which incorporates centrifugal forces in the separating vessel) is a recent innovation in the mineral processing world.
