Production 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.

This mathematical evaluation focuses on iron ore ultrafines for their use in a novel hydrogenbased fluidized bed direct reduction process. The benefits of such a process include reduced CO 2 emissions and energy consumption per ton of product, lower operational and capital expenditure, and a higher oxide yield. Typical samples of iron ore ultrafines, such as pellet feed, are given and ...

This is because iron oxide minerals have been converted to magnetite phase within the roasting time of 4 min. Prolonging the roasting time will lead to the formation of the weakly magnetic iron ore, FeO, resulting in more iron entering the nonmagnetic products. Therefore, the optimum roasting time was considered to be 4 min.
