Coal Washing | Encyclopedia.Com
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.
