Introduction to Mineral Processing Chevron Phillips Chemical

Frothers are liquids that produce the froth or foam on which the flotation process depends. The froth resembles soap suds and provides the physical separation between the mineral(s) floated and the pulp containing the waste. The froth must be strong enough to support the weight of the mineral floated and yet not be tenacious and non flowing.

One significant choice for a mine using the froth flotation process is the selection of an optimal frother to generate quality froth and to maximize the recovery of minerals and metals from ore. Frothers are neutral molecules that absorb at the water air interface, aid in the production of bubbles for flotation, and stabilize the froth for collection and skimming.
