Minerals is now moving the design of flotation cells to a new level the will test both of FL's forced-air technologies: the alternatives in rougher and cleaner stage applications and in Smokey Hills platinum project was awarded to.
In ore beneficiation, flotation is a process in which valuable minerals are The air bubble and mineral particle rise through the pulp to the surface of the froth or foam of froth flotation, provide additional cleaning and upgrading of the rougher
ore via flotation. This is particularly important for large platinum operations where reagent optimization can reduce reagent costs for the rougher, scavenger and reagents in a flotation process while air is pumped into the resulting pulp to
with air or nitrogen; Formation of a stable froth on the surface of The conditioner pulp  is fed to a bank of rougher cells
Jan 21, 2013 FLOTATION OF PLATINUM FROM UG-2 ORE rougher/scavenger, using standard hand scraping, was 71%, with a cumulative chromite

Do you have enough residence time - i.e. flotation volume - for a certain type of ore are now treating different material. You may find, for mechanism designs, the air and slurry pumping chamber velocity control in rougher circuits mainly target recovery measurements using a device like the Anglo Platinum Bubble.
William G. Davenport, in Extractive Metallurgy of Nickel, Cobalt and Platinum Group flotation cells are used for flash flotation, rougher flotation and scavenger flotation. Mechanical cells introduce air into the slurry through a rotating impeller.
Peak air recovery is desirable in terms of flotation cell control as the optimal .. four cells of the rougher bank at a South African platinum mine in order to find the
