Froth Flotation Principles - Metallurgist & Mineral Processing Engineer

Lead Flotation As selectivity is important in the production of lead concentrates, "Sub-A's" are consequently quite extensively used. It is usually necessary to have two or more cleaning stages in a lead circuit and this is achieved on the without the use of pumps, brought about by the gravity flow principle.

Flotation Froth - an overview | ScienceDirect Topics

Flotation takes place by passing finely dispersed air bubbles through an aqueous suspension of particles ( Fig. 17 ). A chemical reagent, called a frother, is normally added to promote the formation of small bubbles. Typical addition rates are in the order of 0.05 to 0.25 kg of reagent per tonne (0.1 to 0.5 lb per ton) of coal feed.
