ABSTRACT:
A slurry, such as of sulfide-type copper ore, is separated into a coarse suspension and a fine suspension. The coarse suspension is centrifuged to separate the solid and liquid phases thereof. The fine suspension may be centrifuged or filtered separately from the coarse suspension similarly to separate its solid and liquid phases. The solid phases of both of these separation operations are then mixed together and can be used for further smelting. It is also possible according to this invention to use a drum centrifuge both for the initial separation into fine and coarse suspensions and for the dewatering for the coarse suspension.
