Hematite gets its intense red color from oxidized iron and magnetic interactions. Hematite has a wide variety of purposes, but no economic significance is greater than the importance of its iron ore (Fe2O3). This is because of hematite's 70 percent iron content, with its remaining 30 percent being oxygen.
