    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. The pellets are fired at a very high temperature to harden them and make them durable. This is to ensure that the blast furnacecharge remains porous enough to allow heated gas to pass throu

The magnetic product removed by the cobbers may go direct to the ball mill or alterna.

  • Definition of taconite pellets Mindat

    After many years of hard work, a process was developed to create taconite pellets. Taconite saved Minnesota's iron ore mining industry. To make these pellets, the hard taconite ore is blasted and then ground down with water to a fine powder. The fine iron rich particles, mostly of magnetite are extracted from the powder by use of magnetism.
