Flotation Principles - Mineral Processing & Metallurgy

Mar 11, 2016· 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 ...

Recovery of pyrite in coal flotation: Entrainment or ...

Under normal conditions, a significant amount of pyrite is recovered in the froth during flotation of high-sulfur coal. To reduce this pyrite recovery, it is first necessary to determine the primary recovery mechanism, because different measures are required for reducing entrainment, locked-particle flotation or true hydrophobic flotation. In this paper, evidence is presented that …
