Small air bubbles are passed through a dilute suspension of coal in water. The hydrophobic coal particles become attached to the rising bubbles and form a froth at the top of the flotation cell. The hydrophilic mineral particles are left behind in the aqueous suspension and are passed to a thickener for mineral matter removal and water recycling. A frothing agent is usually added to help stabilize the froth, which …
Get PriceSelective mineral aggregationhas long been recommended to improve the poor flotation recovery of 20 µm sulfide minerals; however, successfully testing any type ofselectivesulfide mineral aggregation’s effect on flotation recovery in the laboratory on practical plant samples requires reproducing plant cell physics. The energy input per litre and the forces in a laboratory cell are vastly different to a plant cell.
