· Spirals can efficiently treat and recover valuable particles in the size range of 3 mm to 75 μm. The operation of the spiral concentrator is simple and techno-economic, which makes them suitable for the treatment of a wide range of minerals, such as chromite, ilmenite, zircon, rutile, monazite, iron ore, and coal.

From a metallurgy perspective, beneficiation relates to processes used to upgrade the mined raw material or ‘run of mine’ (ROM) ore. The fundamental objective of the application of metallurgy is to produce the materials required for fabrication and manufacturing. In the case of coal the objective is to produce a fuel and/or a reductant. The mining value chain
