The particle size of the raw magnetite ore is in the range of 125–500 μm, which is achieved by mixing 50 wt.% of 125–250 μm and 50 wt.% of 250–500 μm. For the oxidation treatment, 1000 g of the raw magnetite ore was charged into a steel vessel and put into a conventional heat treatment furnace at 800, 900, and 1000 °C for a specific time.
