This research presents three models of froth flotation that recognize flotation as an interfacial phenomenon wherein the rate of solids-surface-area removal is related to the bubble-surfacearea flux. These models use two "streams", air and liquid, within the vessel. The solids within the column are associated with one, or both, of these streams. The procedures and benefits of batch tests for ...

Flotation SGS South Africa

Flotation is an incredibly robust and versatile process that is well accepted around the world. It works equally well on mixed sulfide, oxide, silicate and other ores. It relies on generating a population of bubbles of suitable size that can carry the hydrophobic target mineral (usually but not exclusively sulfide minerals) up to be recovered.
