Process for agglomerating fine coal

Patent:

Abstract

The invention concerns a process for agglomerating black coal in mud or powder form in the presence of a mineral oil product dispersed in water. During this process, the nutty slack is added to a portion - approximately 5 - 15% of its weight in the case of anhydrous coal - of a bitumen emulsion and thoroughly mixed. The emulsion should contain mineral oil bitumen with a penetration value 25/sup 0/ less than 5, or a Conradson value of over 35. In a further finishing process the emulsion contains alkaline naphthenate.
