2019-2-25  quartz and other gangue minerals (Yu et al., 2017). Therefore, low-grade hematite ores must be treated by mineral processing methods (e.g., flotation and magnetic separation) to obtain the iron concentrate. Prior to separation, the iron minerals must be liberated from the gangue minerals through comminution, including crushing and, if necessary, grinding (Liu et al., 2016; Liu et al., 2014; Yin et al.,
