Classification: 209/199

(under subclass 198) Devices in or on which the contact is effected between the material to be separated and the liquid metal which effects the separation are given rotation that will generate such centrifugal force as to promote the separation, generally by forcing the particles of higher specific gravity into the body or bodies of liquid metal in the receptacle.
