Dense Medium Separation Equipment | SpringerLink
Drum-type dense medium separator can be in single-chamber two-product type or double-chamber three-product type. The former has only one chamber, and separation is done by using one density; the latter has two chambers isolated by a partition, and two suspension liquids with different densities are used to generate three …

Dry dense medium separation of iron ore using a gas–solid …
The dry dense medium separation of iron ore based on floating and sinking of ore particles in a gas–solid fluidized bed was investigated using zircon sand as the fluidized medium. The float-sink of ore particles with mean size D ave = 23.6 mm was investigated as the fluidizing air velocity and the float-sink time were varied. It was found …

Jigging or Dense Medium Separation
A considerable debate has arisen regarding the best route for the beneficiation of iron ore. Supporters of jigging technology claim that although the technology is old, due to recent advances in jig control and a better understanding of the separation processes within jigs, it offers significant advantages over dense medium separation, especially in terms of …

The beneficiation flowsheet at Bernic Lake involved dense media separation, pre-flotation of amblygonite, magnetic separation and flotation as illustrated in Fig. 10. The feed size to the dense media separator was −12 + 0.5 mm in which a mixture of ferrosilicon and magnetite with media density of 2.7 was used as a media.
