Frother for coal flotation - Calgon Corporation

In the froth flotation of coal, a froth is formed by introducing air into a slurry which contains the impure finely divided coal particles and water. The flotation separation of coal from the residue or gangue depends upon the relative wettability of surfaces and the contact angle, which is the angle created by the solid/air bubble interface
