Heavy Media Gravity Separation - Mine Engineer.Com

Heavy Media Gravity Separation 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.


tion tests at the Juneau Laboratory. Direct magnetic separation of ore ground to minus-150-mesh or staged magnetic separation of 35-mesh ore with concentrates re-treated at minus-150-mesh resulted in the recovery of 61 to 64 percent of the total iron in a concentrate assaying about 64 percent iron 3.5 percent Ti02 0.3 percent

Concentrating Hematitic Limonitic Iron Ores by High Intensity

However hematitic limonitic and sideritic iron ores with lower magnetic susceptibility require concentration methods other than low-intensity magnetic separation. The ore sample was first of all crushed below 10 mm for easiness of operation with Permroll. The crushed sample was then fed to Permroll without any classifi ion.
