Abstract
In a process for upgrading an aqueous slurry of fine coal by agglomerating coal particles and separating the agglomerates from the slurry the proportioning of the amount of binder used to agglomerate the coal can be substantially optimized by correlating it with the amount of non-agglomerated particles which remain in the slurry, and the ratio of the value of the upgraded coal to the coal of the binder.
