Froth flotation - Wikipedia

This slurry (more properly called the pulp) of hydrophobic particles and hydrophilic particles is then introduced to tanks known as flotation cells that are aerated to produce bubbles. The hydrophobic particles attach to the air bubbles, which rise to the surface, forming a froth. The froth is removed from the cell, producing a...

Introduction to Mineral Processing - Chevron Phillips Chemical

The process of froth flotation entails crushing and grinding the ore to a fine size. This fine grinding separates the individual mineral particles from the waste rock and other mineral particles. The grinding is normally done in water with the resultant slurry called the pulp. The pulp is processed in the flotation cells, which agitate...

A more or less stable layer of froth is maintained on the surface of the slurry. Particles that are attached to bubbles will tend to remain attached at air-water interfaces when the bubble enters the froth layer. Particles that are retained in the froth are recovered at the lip of the froth weir at the edge of the flotation cell.
