The loss of ultrafine coal particles in the tailing not only causes a problem to the recovery of coal but also results in the loss of the purest coal because coal particles at small size are liberated extremely well from raw coal. In other cases, ultrafine coal beneficiation is required to achieve low ash content likewise in coking coals. When minerals are disseminated finely in the coal, it ...
