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...
Reconnaissance of Coal Estimates of the total volume of coal slurry in Indiana range from 94 to 136 million cubic yards An unknown quantity of additional coal-slurry exists at active coal-preparation facilities, in some water-filled impoundments located in the vicinities of inactive operations, in excavated pits of unknown depth, and in graded spoil deposits...
Slurry Densities ρ m = density of slurry (lb/ft 3, kg/m 3) c w = concentration of solids by weight in the slurry (%) ρ s = density of the solids (lb/ft 3, kg/m 3) ρ l = density of liquid without solids (lb/ft 3, kg/m 3) Slurry concentration by weight can be measured by evaporating a known weight of slurry - and measure the weight of dried solids...
Toxic Coal Ash and Coal Slurry Coal mines use roughly 2 million gallons of water daily to wash coal when it comes out of the ground Coal slurry is the contaminated process water that is leftover It contains elevated levels of chlorides, sulfates, arsenic, lead, mercury, and selenium Coal companies dispose of coal slurry ,...
