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.
Jameson Cell is a top-intensity flotation cell aimed at creating better, faster, and more efficient floating systems. It was created by Graeme Jameson, a renowned laureate professor at the University of Newcastle located in Australia. The ground-breaking cell resulted from a partnership with a then fast-growing mining firm, Mount Isa Mines Limited.
