Energy and Environmental Profile of the U.S. Mining Industry Taconite contains low-grade iron in fine specks and bands. It is an extremely hard and flinty - containing about 25 - 30 percent iron. The iron in taconite occurs principally as magnetite and hematite and finely dispersed with silica in sedimentary deposits. Taconite is found in large
Increasing iron ore demand, coupled with the depletion of high-grade hematite ores in the United States, after World War II led to development of lower-grade iron ore sources, principally the utilization of magnetite and taconite. Iron-ore mining methods vary by the type of ore being mined.
