Froth flotation is a complex process with many subprocesses, involving three phases: solids, aqueous medium, and air bubbles. The principle behind froth flotation is the attachment of the hydrophobic particles to air bubbles to be floated and recovered to the concentrate, while the hydrophilic particles are wetted by water and stay in the ...

2. Introduction Floatation is an extractive process where various minerals can be selectively extracted. Flotation is a selective process and can be used to achieve specific separations from complex ores. For example, in poly-metal ores such as Pb-Zn- Cu, floatation allows separate extraction of Pb, Cu and Zn.
