Claims19
A method of collecting fine particle coal, the method comprising:
- dewatering a clean coal effluent slurry having a solids content of from about 3% to about 20%, by weight, to produce a fine particle coal having—
- (i) a particle size of 1000 μm or smaller, and
- (ii) an ash content of from about 3% to about 28%, by weight;
- wherein the dewatering of the clean coal effluent slurry comprises centrifuging the slurry in a solid bowl centrifuge, the centrifuge comprising a rotating bowl, an internal scroll, and a weir plate.
