The processing of heavy minerals and coal is often carried out using spiral classifiers. Processing of iron ore to separate coarse iron oxides such as hematite from light gangue mineral, such as quartz, is carried out in circuits with several hundreds of rougher, cleaner and re-cleaner spirals (Bazin et al., 2014).

For processing of sand minerals normally spirals are being used at onshore where the bottom or base of the plant remain stable and, the heavy minerals (grains with specific gravity generally greater than about 2.9) migrate to the inside of the spiral while the lighter materials (shell, quartz, phosphate, etc.) will be carried in the water stream toward the outside.
