Abstract
A relatively dry coal product can be prepared from aqueous slurries of respectively fine and granular coal particles by agitating the fine particles with water and binder to form mechanically separable agglomerates and, before separating them from most or all of the liquid in which they were formed, mixing those agglomerates with the relatively large coal particles in a specified proportion, and then mechanically dewatering the mixture.
