Biosolids Technology Fact Sheet Gravity Thickening - EPA

Gravity concentration is used for processing coal fines downstream of a cyclone, following desliming and sizing screening. After gravity concentration, coal streams are fed into dewatering screens, and then a Siebtechnik centrifuges. Gold beneficiation. Gravity concentration spirals are optional in gold processing, used for carbon degritting.
