Michigan iron ore averages about 51 per cent iron natural. Its parent rock, the iron formation, averages 20 per cent to 25 per cent iron. The ore is a product of a natural concentration of the iron by removal of its associated silica Ore is not found everywhere in the parent material. It represents less than one per cent of the total volume of
Mining Iron Ore Mining iron ore begins at ground level. Taconite is identified by diamond drilling core samples on a grid hundreds of feet into the earth. Taconite rock comprises about 28 percent iron; the rest is sand or silica. These samples are analyzed and categorized so that mining engineers can accurately develop a mine plan.
