Heavy Media Gravity Separation Mine EngineerCom

Heavy Media Gravity Separation Heavy media gravity separation involves using a mixture of fine media material such as magnetite SG 51 or ferrosilicon SG 68 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
