ABSTRACT:
A new heavy liquid parting medium comprising an emulsion of water and a substantially water immiscible heavy parting liquid for use in beneficiating ores by gravity separations such as sink-float processes. The specific gravity of the emulsion parting medium can be adjusted by proportioning the relative amounts of water and the substantially water immiscible heavy liquid. As-mined coal is beneficiated using a water-trichlorofluoromethane emulsion as the parting medium in a sink-float separation process.
