Froth flotation process introduction-Ore Beneficiation

Froth flotation process introduction. Flotation process, named as froth flotation process, is based on difference of surface of various minerals, by means of buoyancy of the bubbles from the slurry, to sort minerals. Its main process is that the bubble with selective slurry with incompact adhere on the liquid interface rise, then scrape foam formed on the surface of pulp.
