Introduction. 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).

It is evident that D 50 c increased with increasing particle loading for both silica and iron ore systems. For silica, the spiral classifier had a cut size in the range of 82-108 μ m, whereas for iron ore the spiral classifier had a cut size of 38-66 μ m. Hence, there is a gap between the range of D 50 c values observed in silica and iron ore ...
