flotation separator for mineral ore concentrating project

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...
