A system and method is provided for beneficiating, or "cleaning", ultrafine raw coal with spiral concentrators. The inventive system includes multiple pre and postclassifiion systems to size the finer sized raw mineral to develop a presized mineral fraction within a first size range (approximately mm by mm). The presized mineral fraction is fed to at least one spiral ...
Spiral concentrators have been widely used in coal preparation plants in Illinois and elsewhere to clean the 1 mm x 150 micron particle size fraction.

Spirals exhibit one of the most complex flow regimes among gravity separators. Spiral concentrator flows have a freesurface, shallow depths (b1 cm) and display laminar to increasingly turbulent behaviour. The flow behavior is radially outwards with velocities reaching about 3–4 m/s (HollandBatt, 1990, 1992, 1994, 1995).
Spirals in coal processing are high capacity, lightweight fiberglass construction, use no power, use no reagents and effectively remove pyrites from coal. Most spirals are available in single start, double start or triple start versions, giving two or three times the capacity for the same floor space. Single spiral test stand is also available.

· Spiral separator is considered to be the most effective gravity separator, capable of processing a wide range of minerals such as coal, iron, chromite, gold, zircon and other heavy minerals ores. Combined action of gravity, hydrodynamic forces and the centrifugal forces that act on the solid particles, causes the stratifiion of gangue and pure mineral particles.

Spiral concentrators are used in coal preparation plants to clean the 1 mm x 150 micron particle size fraction, which is too fine to be effectively cleaned by heavy medium cyclones and too coarse for froth flotation cells or flotation columns. A spiral is a flowing
Spiral Concentrator Appliion for Ultrafine Coal Cleaning Recent studies have found that spirals such as the SX7 can provide an effective gravitybased separation performance for 100 mesh coal. Required volumetric flow rate is around 15 gpm/start and feed solids content should be nearly 15% by weight. Currently, two coal
