Magnetic separation is used to enrich iron ore samples that demonstrate either para- or ferromagnetic behavior (Flippov et al. 2014). Magnetic separation can be performed on wet or dry material, with wet being a slurry (Flippov et al. 2014). Magnetic separators are broken down into two categories: high and low intensity (Flippov et al. 2014). Low

The removal of "tramp" iron from feed belts can also be regarded as a form of low-intensity magnetic separation. However, tramp iron removal is usually accomplished by means of a magnetic pulley at the end of an ore conveyor (Figure 13.12) or by a guard magnet suspended over the conveyor belt (see Chapter 2).Tramp iron removal is important prior …
