Introduction to Mineral Processing cpchem

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.
