More ores are treated using froth flotation cells than by any other single machines or process. Non-metallics as well as metallics now being commercially recovered include gold, silver, copper, lead, zinc, iron, manganese, nickel, cobalt, molybdenum, graphite, phosphate, fluorspar, barite, feldspar and coal. Recent flotation research …
This will make the bond between the molecule and the bubble as well as the bond between the particle and the molecule weak. Both will begin to fall free of the bubbles. As these particles that do fall off descend into the cell they become trapped by the tighter smaller bubbles that are caused by the pressure of the slurry in the cell.
