ABSTRACT:
A size fraction of coal is physically cleaned by separating the coal into a low density fraction containing relatively small amounts of inorganic constituents and a high density fraction containing relatively large amounts of inorganic constituents, crushing the low density fraction to produce smaller particles, separating the smaller particles into a low density fraction and a high density fraction and recovering the low density fraction as clean coal product.
