Flotation Principles - Mineral Processing & Metallurgy

Metallurgical ContentSURFACE TENSIONBULK-OILOIL AND AIRBUBBLESCOAGULATIONFROTH 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 .
