Explaining the Process of Froth Flotation
Application to Commercial Flotation Processes Film Flotation. Pulp with or without oil or acid is fed gently, at an acute angle, onto the surface of a body of still water. The sulphide floats and the gangue sinks. Possible cases: Case 1.—Sulphide, gangue, water. Case 2.—Sulphide, gangue, water, oil. Case 3.—Sulphide, gangue, water, acid.Web

Flotation in Water and Wastewater Treatment
Flotation is known as a separation process, based on the introduction of gas bubbles as the transport medium. Suspended particulate matter, being hydrophobic or conditioned to be so, is then attach to the bubbles and moves toward the water solution surface—i.e., contrary to the direction of gravity [1,2].Different bubble generation …Web

Flotation Principles
Flotation Principles. Flotation, in its latest phase, is a process of concentrating ores by frothing. When crushed ore, previously mixed with water and a relatively minute addition of oil, is agitated violently in the presence of air, a froth is formed. This froth, rising to the surface of the liquid mixture, is laden with sulphides or other ...Web
