Coal Washing Encyclopedia

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.

As expected the results of these studies suggest that the degree of liberation that is obtained is coal specific, and hence yield improvements are also coal specific. Hence a quantitative method of investigating this issue is required. INTRODUCTION
