A novel scale-up approach for mechanical flotation cells
The industrial cell model con- perfectly mixed industrial cell (N = 1) and the flotation rate (kB) siders two zones: collection and froth In this approach, the batch in a laboratory batch cell, flotation is conducted to obtain the maximum rate constant by fast removal of the froth zone
Column Flotation - an overview | ScienceDirect Topics
Modern flotation columns were developed in Canada in the early 1960s (Boutin and Wheeler, 1967) and were first used for cleaning molybdenum concentratTwo column flotation units were installed in the molybdenum circuit at Mines Gaspé, Canada, in 1980, and excellent results were reported (Cienski and Coffin, 1981)The units replaced the multistage cleaner banks of mechanical cells
Ferced aeration mechanical flotation machin Ferced aeration mechanical flotation machines are flo ta tion m a chines, in which pulp aeration is done by compressed air consumption, but dispersion of air and pulp mi xture is made by a rotating rotor DOOR-OLIVER cells (, USA)
