Iron ore mining hematite

The XRF test showed that the Lhoong iron ore contain Fe2O3 (93.88%) in association with other isomorphous impurities, such as SiO2, MnO, and Al2O3 in varying proportions. Compare to XRD results, it was consistent with XRF, the phase compositions of iron ore are mainly hematite (Fe2O3)

    Iron Ore Statistics and Information - USGS

    Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world's iron and steel industries

    Hematite, an oxide of iron (Fe2O3), is also known as red iron ore and in 1967 was designated as the State Mineral by the Alabama Legislature with Act no. 503 . Approximately 375 million tons of hematite was mined in Alabama from 1840 to 1975 (when mining in Alabama ceased), contributing to the development of Birmingham as an industrial center
