Chromite Beneficiation Process
The tailing from the scavenger Mineral Jig is directed to a 30″x 13′ Simplex Cross-Flow Classifier which discards a waste product as a final tailing at minus 65 mesh and the sand product is returned to the rod mill for further grinding. A SRL Sand Pump is used to pump the Mineral Jig Tailings to the Cross-Flow Classifier. Chromite Process ...

Thermo-adhesive Separation: a Novel Dry Coal Beneficiation …
Water is the mainstay for beneficiation of fine size coal and minerals; however, it is also the least desirable constituent in the final product. The basic concept of the novel process described in this paper is based on the differential surface heat conduction/absorption capacity of individual particles, which differs for different species of minerals. When a mixture of fine …
