The use of a gently uprising, aerated fluid greatly reduces the turbulence commonly found in other flotation cells, allowing the effective flotation of coarser particles (Kohmuench et al., 2018). Fluidised bed flotation is advantageous as it can reduce the need for finer grinding, reduce grinding costs, and it accepts feed with very high solid ...

Plants operating with forced air cells have often noticed that the best results are achieved using individual and varying air feed rate in each cell. In traditional flotation mechanisms the air feed is limited by the reduction of power draw and mixing, or by reduced dispersion of air making the froth surface unstable and causing the froth to ...
