Review on advances in mineral processing technologies suitable
2022年4月1日· 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 fractionsno flotation can occur Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5 Figure 5: Simplified schematic of a conventional flotation cell The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator1 Froth Flotation – Fundamental Principles
