Size recovery curves of minerals in industrial spirals for processing
Spiral concentrators are gravity based separation devices used for the preparation of coal, iron and other heavy minerals ores (Wills, 1992).The classification of the particles in spirals is based on the combination of gravity, centrifuge, drag and Bagnold forces (Atasoy and Spottiswood, 1995, Burt, 1984, Bouchard, 2001).The spirals operate on both particle size and …

Spiral Separator | Spiral Concentrator
Working Principle. Spiral Separators, which are also called Spiral Concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium. The heavy frictional forces slow their velocity. As a result, faster particles higher up in the flow.

A preliminary study of particle separation in spiral concentrators
Spiral concentrator is essentially a flowing film gravity concentrator, where the combined action of gravity and hydrodynamic forces due to the circulating flowing film is brought to separate gangue from pure mineral. Spiral concentrator's full-fledged commercial use started in the early 1940s.

Principles of spiral concentration
Spirals are used for gravity concentration of minerals and of late these have been extensively and effectively used for iron ore processing. Their widespread use is mainly due to lower capital cost and higher efficiency to treat feed material in the size range of 3 mm to 45 µm.Although operating a spiral is quite simple its design is quite challenging for specific …
