METHOD FOR FROTH FLOTATION

摘要

A method of froth flotation where a pressurized stream of feed slurry and a pressurized stream of air are delivered to a contactor vessel. The feed slurry includes a mixture of particles of oil or hydrophobic materials and water. The feed slurry and the stream of pressurized air are maintained within certain flow and pressure parameters a nd allowed to intermix within the contactor vessel to permit the attachment of air bubbles to the particles of oil or hydrophobic materials thereby forming particle-bubble aggregates. The contents of the contactor vessel are discharged into a separation vessel where said particle-bubble aggregates form a froth for removal as a concentrate.
