Oct 23, 2014 On this density, the magnesium and waste will float while the other metals will sink. The metals which sink are sent to a second separation drum with a medium at 3.2SG. On this density, aluminum will float and the heavy metals will sink. The three materials coming out of the material are then rinsed after the separation process.
Media is fed into the pool area of the heavy media drum via the feed chute. As a result of the differing densities of the feed, separation occurs in the pool area of the drum. The less dense particles will float and exit via the overflow weir there they report to a drain and rinse screen to recover the drum medium, while the denser particles ...
Dense medium ferrosilicon is a fine metal powder, with size distributions below 255 micron. It is used in Dense Medium Separation processes, where the powder is mixed with water to the desired medium density, and added to a DMS plant. The separation takes place in either a static Drum or a dynamic cyclone separating unit.

Drum separators. Heavy media drum separation HMS also known as dense media separation, is a process used to separate materials that have different specific weight. A heavy media fluid of the correct density is pumped and kept in circulation inside a rotating drum.
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 materials to float, and other high density materials to sink.
For recovery of magnetite and ferrosilicon in dense media separation processes a special Lims models, DM and CR, are designed to provide highest possible recovery of the media. For all wet processing separators the magnet system is selected to achieve best performance in each individual case.

Lab and small-scale testing of dense media separation DMS has been a difficult task to accomplish as batch testing relies on heavy media solutions of high specific gravity SG salts that are expensive to purchase. Piloting requires tonnes of material to run through even the smalled of continuous DMS units.

DMS working principle. The heavy medium separation method is an advanced gravity beneficiation method. Following the Archimedes principle particles smaller than the density of the heavy medium will float, and particles larger than the density of the heavy medium will sink in the medium. The fluid movement and particle sedimentation are no longer the main factors contributing to the layering, and the property of the medium itself is an important factor in the separation.
