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 first step in all beneficiation plants is converting crude ore into a medium that can be effectively fed into a concentrator. This generally involves some degree of primary crushing, as well as screening or classifying the ores into sizes - either oversized or minus-grade and undersized ores - which were amenable to concentration. At the Coons-Pacific plant, …
