Coal is cleaned at preparation plants. The main goal of preparation is to remove mineral impurities in the coal that lower the coal's heating value and increase sulfur emissions when the coal is combusted. There are several types of density separation processes in preparation plants, but the most common floats crushed coal in a fluid.
