Imhoflot pneumatic flotation technology has evolved through 25 years of industrial applications. This has led to the development of the patented Imhoflot G-Cell where centrifugal forces are used in the cell to quickly separate the phases after mineral collection and therefore considerably reducing the size of vessels required.

The Imhoflot G-Cell is an innovative pneumatic flotation process that can be used to recover this previously wasted middlings stream. The technology uses centrifugal forces to assist in the separation of the froth phase from the tailings and consequentially reduce the residence time in the separating vessel. This paper describes the testing ...
