Abstract
A waterless method of separating minerals and a mobile mineral separator are described in which preheated mine products are continuously separated from associated mine refuse by sink/float washing in a heavy-liquid bath which has been heated to its boiling point. The heavy liquids will usually be halogenated organic liquids or liquid mixtures. The separated product and reject fractions are withdrawn by augers to drainage hoppers where most of the heavy liquids are removed for return to the bath. Final removal of the heavy liquids from the mine products and reject fractions is accomplished by vaporization as the product and the reject fraction move by additional augers through heated pipes. The vaporized heavy liquids are collected in air-cooled or otherwise cooled condensers and are returned to the bath. The heavy liquids are essentially completely recycled.
