During the stirring mill experimentation, the parameter settings were a 90% medium filling rate, a 50% grinding concentration, a material ball ratio, a 3:2:5 medium ratio (10:15:20 mm) and a 110 rpm stirring speed. The field strength of the second stage magnetic separation was 1800 Oe. The experimental outcomes were presented in Fig. 12.
