Effects of dispersants on preparing coal pitch water slurry

, 2015
344-350The coal pitch water slurry(CPWS) has been prepared with solutions of dispersants and medium temperature coal tar pitch powder corresponded with “bipeak trifurcated distribution” made by cryogenic grinding technology.

Thickening fine coal refuse slurry for rapid dewatering and enhanced safety [PDF]

"To decrease the potential for fine coal waste slurry impoundment failures, the Bureau of Mines investigated a new disposal technique. The fine coal waste slurry is rapidly thickened (i.e., dewatered) and deposited on a slightly sloping surface.
