摘要：The present invention relates to methods for beneficiating a banded coal of the type wherein a substantial portion of the ash constituents is within the cleats. The method includes subjecting a comminuted coal feed, including coal and ash and having a particle size of about -13.5 mm, to a density separation process to separate the
comminuted coal feed, using a separating gravity value of from about 1.35 up to about 1.9, into a beneficiated coal fraction and an ash containing gangue fraction. The method may include the initial steps of subjecting a coarse coal having a size of up to -150 mm to a density separation process to separate the coarse coal into an initial light coal-containing fraction and an initial heavy ash containing gangue fraction; and subjecting at least a portion of the initial light coal-containing fraction to a comminution process to form the comminuted coal feed. The invention extends to a coal product produced by said methods.
