Ideally, coal slurry consists only of crushed coal and water, which can be efficiently separated. In practice, the separation is significantly costly due to the large amounts of water needed and wastewater generated by the process. Furthermore, the slurry consists also of very fine coal dust that results in a waste called blackwater cannot be purified by a water treatment plant ...
Coal refuse is any waste that results from the processing and cleaning of the coal, including slurry, culm, slate, clay or other materials associated with or from a coal seam. Toxic substances in the wasteincluding arsenic, mercury, chromium, and cadmiumcan contaminate drinking water supplies and damage vital human organs and the nervous system.
The preparation of waste liquid coal water slurry (WCWS) can aid with environmental protection and resource utilization. In this study, xanthan gum was selected from 11 types of additives because it overcomes the problem of solution incompatibility during the .

Clean Coal Dewatering: The clean coal in pit is first dewated by bucket elevator, secondly dewated by centrifuge machine, and then transported to the clean coal storage yard by belt conveyor as the final product together with the clean coal on the screen. Flotation: The overflow from the pit enters the flotation feed pool and is pumped to the pulp preprocessor through the slurry pump.

Preparation Edit. To transform the coal ash into a slurry, coal is separated from noncombustable components and can be fractionated by particle size as slurry can be transferred by pipeline or with specialized pumps such as a progressive cavity pump to pump the highly abrasive, corrosive and viscous coal slurry. More than 7 billion tons of coal are mined per year (2010), using ...
