Dense medium separation DMS, synonymous with heavy medium separation HMS, is a form of gravity concentration technology involving float-sink separationHigh G-Force Gravity Concentrators. The higher the G-force, the smaller the minerals you can recover with a given technology. All of the Falcon Gravity Concentrators are high G-Force devices that achieve forces from 100-600Gs. When these forces are applied to a mineral feed, particles as fine as 3 microns in size can be selectively recovered.Two Stage Concentration The Super B enhanced gravity separator is the first significant improvement to the MacNicol design in 60 years. It was conceived in 1994 as the combination of the best of both technologies.Gravity separation is the earliest mineral processing method.
