What Are the Uses of Magnetite

· It is also used in coal mining operations as a slurry with water to remove the heavier impurities by allowing the less dense coal to float to the surface The magnetite can be reused in this process 90 percent of the time Magnetite is also used as a source of iron to manufacture iron based chemicals and fertilizers
