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).

1. Introduction. Iron ore pellet sizes are a factor in the efficiency of the blast furnace process in the production of steel. Overly coarse pellets affect the blast furnace process negatively, but this effect can be minimised by operating the furnace with different parameters [1].An on-line system for the measurement of pellet sizes could improve …

We use randomised hold-out to ensure the generalisation of our classifier, and test it against known ground-truth information to demonstrate its ability to detect iron ore and non-iron ore locations. Our classification strategy is based on the heterogeneous nature of the data, where a well-defined target "iron-ore" class is to be separated ...
