The Guide of Flotation Defoamers


Flotation agents are chemical agents used in the mineral flotation process which can adjust the surface properties of the minerals, increase or decrease the floatability of the minerals, and make the pulp properties and foam stability more conducive to mineral separation. Common flotation agents are collectors, foaming agents, inhibitors, activators, dispersants, flocculants and defoamers.

Flotation - Simple English Wikipedia, the free encyclopedia


Flotation is a process where gas bubbles are injected at the bottom of a tank containing a mixture of a liquid and solid particles to separate the solid particles from the liquid. When the gas bubbles move along the liquid mixture, the solids particles stick to the surface of the bubbles. The bubbles form a foam at the surface of the liquid: this foam contains the solid particles, so after the ...
