ABSTRACT:
A method for recovering coal from a mixture containing fine particles of coal, the mixture including fine coal particles, water, and impurities, the method including feeding the mixture to a first liquid/solid separator that removes relatively large pieces of material from the mixture producing a first stream containing recoverable fine coal particles, and pumping the first stream from the first liquid/solid separator to at least one second liquid/solid separator, the at least one second liquid/solid separator separating recoverable fine coal particles from the first stream producing a product flow containing fine coal particles and a discharge stream containing, e.g., water and impurities. In one aspect, the coal in the product flow is then dried and/or pelletized. In one aspect fine coal particles in the product flow have a largest dimension of less than 100 microns. In one aspect, fine coal particles in the product flow have a largest dimension of at least about 40 microns.
