  • Flotation Collectors - Mineral Processing & Metallurgy

    Flotation Collectors. Simply said; a Flotation Collectors is a chemical used to make the surface of minerals, which is metallic, hydrophobic or in layman''s term ''afraid of water'' or ''water hating'' as others like to say. This chemical used will behaved, in a way, as a wax would when you applied it to your car.

    ABSTRACT The reverse flotation of calcareous phosphate ores, at acidic pH, usually uses anionic collectors such as oleic acid (Ol) and sodium dodecyl sulfate (SDS). However, using a mixture of two anionic collectors is very rare. In the present paper, a mixture of oleic acid and sodium dodecyl sulfate, with a ratio 1:1, was prepared.
