Kinetics of flotation CONCENTRATION OF MINERALS

Flotation kinetics (from the Greek Kinētikós driving) is studying the regularities of flotation process at the time, the rate and the flotation mechanism. Kinetics of flotation reflects the flotation results in variable states and is characterized by dependency of the recovery R of floatable mineral in concentrate from time t, R = f (t).It allows a quantitative description of the ...

Flotation Circuits. Flotation circuits are typically comprised of rougher, scavenger and cleaner flotation banks. Rougher and scavenger banks are focused on recovery and thus provide maximum residence time. Rougher banks can be large with the number of cells being 5 or greater. Scavenger cells are the last line of defense for avoiding losses.
