Flotation Cell Design: Application of Fundamental

2016-6-7  The frothSotation process is commonly employedfor the selective separation of a mineral speciesfrom a liquid}solid suspension of both valuableand unwanted gangue mineral particles. The valuablemineral species (which needs to be separated) isrendered hydrophobic by controlling its surfacechemistry to provide the potential conditions forthe attachment of the particles to air bubbles. Thebubbles and particles are made to interact with eachother inside aSotation machine. The Sotation ma-chine, depending on its operating conditions, pro-vides an environment for the bubble}particle attach-ment and permits levitation of bubble}particle ag-gregates to the froth. The manner in which bubblesand particles interact with each other depends on thecell operating

2009-8-27  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 stator. The air is then dispersed as bubbles through the slurry, and comes in contact with particles in the slurry that is drawn through the stator.
