How to Do the Coarse Coal Slime Separation

Generally, the particle size of fine coal is between 0.25-2mm and it's difficult to separate by flotation method is called coarse coal slime. Regardless of jigging or dense medium separation, the separation accuracy of materials 2mm fraction size is poor, and the separation size range of flotation process is restricted by the adhesion of bubbles and particles.

Desulfurization kinetics of coal combustion gases

Introduction of limestone into the furnace is inefficient for combustors that use a high combustion temperature, such as pulverized coal combustor system (Slack and Falkenberry, 1970). The fluidized-bed reactor is a technology that has a high rate of mass and heat transfer, and it has proved to be effective by a lot of published research (Renz, 1981; Valk, 1995).

Note the considerable range for coal in different forms (mean particle size), but in ALL forms, the bulk density is less than water. For coal averaging 50 lb/cu ft, 40 cu ft/ton is sufficient for designing storage, but dust or extremely finely ground coal could be as low as 35 lb/cu ft, requiring around 58 cu ft/ton.
