From Micro to Nano: Grinding Natural Magnetite Ore
For grinding in the planetary ball mill (PM100, Retsch GmbH, Haan, Germany; grinding jar and 1 mm beads made from yttrium-stabilized zirconium oxide), we chose a bead-to-ore volume ratio of 2:1 the magnetite ores can be basically considered a two-phase mineral consisting of magnetite and quartz. 2.2. Grinding Test. In this paper, the wet ball milling process was used in the laboratory ball milling test. Before grinding, the ball mill was kept idle for 10 minutes and then washed together with the grinding media. Three types of ores wereThe Effect of Grinding Media on Mineral Breakage Properties of
