COAL FLOTATION - Mineral Processing & Metallurgy

1. Introduction. Froth flotation is a technique that is used for fine coal beneficiation. Since froth flotation relies on the surface properties of coal for the separation of particles, coal petrology plays an important role in the process .Arnold and Aplan measured contact angles for several US coal samples to quantify the hydrophobicity of individual coal macerals.

Coal washing is accomplished by one of two major processes, by density separation or by froth flotation. Both processes depend on the fact that the particles of which a coal sample are made have different densities. When water, for example, is added to the sample, particles sink to various depths depending on their densities.
