Flotation Collectors Mineral Processing & Metallurgy

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. After wax (or hydrophobic agent) is adhered to the surface, that surface with see water pearl-away.

Flotation separation of quartz from apatite and surface

However, at high collector concentration (i.e., 1 × 10 −3 M), since the contact angle of apatite was observed to be 46° at pH 3, flotation separation would be difficult as both the particles are hydrophobic. Thus, surface analyses of the particles and flotation tests were performed systematically at pH 3 and pH 7.

For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles.
