Their operation is straightforward, with low capital and operating expenditure. In India, they are used to process iron ores, chromite ores, beach sand minerals, coal, etc. A spiral concentrator does not require any dense media such as magnetite or ferrosilicon. Harmful chemicals are also not necessary to beneficiate fine-sized particles.

Fine mineral spiral separators are used to treat particles down to 30 μm size [28]. The key factor in the design of spiral separator is overall control of turbulence (Reynolds numbers) across the entire trough to ensure the conditions throughout the flowing medium. As a result of which controlled settling takes place to make efficient separation.

Gravity Spiral Concentrator Working Principle. The gravity spiral circuit is designed to extract and concentrate "coarse gold' from the recirculating load in the mill grinding circuit and hence prevent a build-up within that circuit and the eventual escape of some of that gold into the C.I.L. tanks and thereon into the final tails.
