Heavy Media Separation Process

Heavy Media Separation Process

The heavy-media separation process or HMS employing ferrous media usually ferrosilicon and or magnetite is the most generally used process for sink-float separations A stable medium over the range of specific gravities from 1 25 to 3 40 can be maintained within close limits and is cleaned and recovered by magnetic means
