Coal slurry

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.As blackwater cannot be purified by a water treatment plant
