Froth Floation | Hoffman & Lamson Solutions

The froth is removed from the cell, producing a concentrate of the target mineral. Froth flotation efficiency is determined by a series of probabilities like those of particle-bubble contact, particle bubble attachment, transport between the pulp and the froth, and froth collection into the product launder.
