PDF FINE REFUSE AND ULTRAFINE COAL Dewatering Ultrafine Coal by Vacuum Filtration

Dewatering has been a technical and economical barrier to the stabilization of coal refuse tailings and the utilization of ultrafine coal particles from coal preparation Conventional Although the effects of size and wettability have been well recognized the studies on dewatering of ultrafine 25 181 m and fine 500 181 m coal have not yielded much quantitative data Gray in his vacuum filtration tests on dewatering of fine coal used a series of narrow sized fractions of coal to study the influence of a minus 63 181 m fraction on dewatering of a minus 600 181 m size
