3.2 Gravity based separation. The surface-based flotation process may not be favourable for all types of coal fines. The enhanced gravity separators (EGSs) can do efficient upgrading of ultrafine particles down to below 38 μm for most coals. The separation efficiency falls as the fine particle size decreases.
Gravity concentration is mostly used for coal, gold, iron ore, platinum, chrome and mineral sand beneficiation. Coal . Gravity concentration is used for processing coal fines downstream of a cyclone, following desliming and sizing. After gravity concentration, coal streams are fed into dewatering screens, then into a Siebtechnik centrifuge.
