Dense Media Separation using Heavy Liquids. Heavy liquids such as LST (lithium heteropolytungstate) or SPT (sodium polytungstate) with higher densities are used to separate heavy mineral concentrates. Denser or heavier minerals in the sample sinks in the liquid while lighter fraction floats.

Subsequent mineral separation by density was achieved using a -table. The heavy mineral fraction was then further parted by magnetic separation (Frantz magnetic separator) in two steps (0.5 A and 1.5 A current). Minerals that were not magnetic at a current of 1.5 A were further separated by heavy liquids (3.32 g/cm 2). The mineral ...

Due to the relative scarcity of heavy minerals in sediment, they normally require separation and concentration [16,17,18,19] and are traditionally sorted, hand-picked, and identified using optical microscopy [20,21,22]. The latter is time-consuming and requires a specialised knowledge of mineral optical properties.

other valuable heavy minerals such as ilmenite, leucoxene, rutile, zircon, and staurolite. The results of two different pilot-scale in-plant testing investigations are discussed. In general, quartz rejections in excess of 80% were achieved while maintaining TiO 2 and heavy mineral recoveries above 98% and 99%, respectively.

Spiral separators, or spirals for short, are a versatile method of gravity separation that can deal with a comparatively wide size range. Separation is achieved as a result of centrifugal forces induced by slurry running down the spiral, which forces lighter minerals to the outer bend whilst heavier minerals stay closer to the central axis of the spiral.

The spiral chute mainly uses the inertial centrifugal force generated by the minerals of different densities in the spiral rotation to achieve the separation of light and heavy minerals. Because of its simple equipment structure, low power consumption, and large processing capacity, it is widely used in the gravity separation process.
