Dense medium beneficiation of fine coal revisited SAIMM

Dense medium beneficiation of fine minus 05 mm coal is not a new concept and has been used in South Africa previously The dense medium fine coal plant at Greenside Colliery operated for almost 18 years and despite proving a difficult plant to operate did succeed in producing a fine coal product with a low ash content of 7 No other

Beneficiation and Balling of Coal 911metallurgist

The spherical agglomeration process provides an attractive method for the cleaning and recovery of fine coals in the form of compact oil bonded pellets In treating a washery effluent containing 50 minus 20 micron material by this technique the slurry was first mixed under vigorous agitation with oil to deash and dewater the fine coal The flocculated coal pulp was then formed into larger
