Heavy Media Gravity Separation - Mine Engineer.Com

Heavy media gravity separation involves using a mixture of fine media material, such as magnetite (SG 5.1) or ferrosilicon (SG 6.8), suspended in a slurry of water, to produce a media slurry with a specific gravity that will allow low density material(s) to float, and other high density material(s) to sink. T he SG of separation is the SG of the media slurry, and can range from 1.45 (for coal ...
