Abstract
The present invention pertains to a two-stage agglomeration process for coal fines in the form of a pumpable slurry. The slurry is selectively agglomerated in the first stage by the addition of a hydrocarbon binder and the bulk of the water separated from the resulting agglomerates. Improved agglomerates are obtained in the second stage where those from the first stage are resubmitted to turbulent motion in hot water, which is drained from the agglomerates and recirculated thus reducing energy requirements.
