ABSTRACT A coal cleaning process for removing substantial mineral matter from high ash-containing coals using coal-derived liquid by using coal-derived liquid for agglomeration. In the process, particulate coal is mixed with sufficient water to provide a flowable slurry, and coal-derived hydrocarbon liquid is intimately mixed with the coal-water slurry to provide agglomerated coal particles. By screening the re- sulting coal-water-hydrocarbon liquid mixture, a portion of the coal containing increased mineral matter settles, and a coal-oil upper portion of agglomerated coal particles having decreased concentration of mineral matter is removed and dried to remove water to less than about 25 W % remaining. The cleaned and dried coal-oil material is advantageously fed to a coal liquefaction process to produce hydrocarbon liquid and gas products, and a coal-derived hydrocarbon liquid is recycled to the coal cleaning step to produce the agglomerated and cleaned coal particles.
