concentrating fluorspar by froth flotation

TECHNICAL NOTES 9 FLOTATION - Mineral Tech

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. The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles.
