    To process taconite the ore is ground into a fine powder the magnetite is separated from the gangue by strong magnets and the powdered iron concentrate is combined with a binder such as bentonite clay and limestone as a flux. As a last step it is rolled into pellets about 10 millimeters in diameter that contain about 65 iron.
