Abstract

A process and apparatus for producing coal-water fuel comprises crushing and primary grinding of the coal to form a liberated granular material, multiple stage froth flotation of the granulated coal to reduce its ash content and pyritic sulphur content. The resulting product from the froth flotation opera­ tions is dewatered to yield a product having a selected solids content. A stable slurry is then produced from the product by establishing a selected particle size distribution. Refuse ac­ cumulated from the various previous steps is collected, dewa­ tered and the water is clarified for use in the process steps.
