ABSTRACT:
Mine-run lignite having an unsalably high content of ash-producing clay is treated selectively to shatter the more friable portions; the effluent from the shattering operation is classified by size; at least the classification containing the smallest particles is discarded; and particles of size larger than those discarded are combined to produce a mixture of lower ash producing clay content. Preferably, the classified effluent is separated into a first portion containing the larger, salable particles; a second portion containing medium-size particles which contains too much clay to be readily salable with the medium-size particle mixture subjected to further treatment such as jigging or heavy media separation to yield a product of clay content that is salable; and a third portion of smaller size particles which is discarded.
