In the case of magnetic separation, such as for iron minerals, there are several crushing and grinding stages with the tailings passing through a froth flotation process (Schreiber et al., 2021). For instance, in highgrade magnetite ore, the grain size of the gangue minerals (tailings) after magnetic separation is in the 4575 µm range ...
