ABSTRACT:
A method for dewatering froth fines obtained during the separation of coal, in which a discontinuously operating sieve scraping centrifuge is filled with the froth fines, the mixture is centrifuged at a low rotational speed to remove a major portion of the liquid and to deposit a layer of solid material which acts as a filter aid, and the remaining mixture is then centrifuged at a high rotational speed. The first run-off is reintroduced into the centrifuge to reduce its high solids content.
