For instance, 20 min ultrasonic treatment of CS resulted in a hematite recovery of 15.6%, which is 31.1% lower than that obtained without ultrasonic treatment. However, since further increase in the ultrasonic time (>20 min) did not give lower hematite recovery, 20 min ultrasonic time was selected when preparing MS in subsequent investigations.

The fine grinding results in the generation of ultra-fine mineral particles (typically less than about 10 µm), possessing high specific surface areas. The ultra-fine value minerals do not respond well to flotation due to the small particle size and inertia, causing a low recovery (Li et al., 2020a, Li et al., 2020b, Li et al., 2020c, Sadangi ...
