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
