Characterization of iron ore by visible and infrared

Jan 01, 2015 Reflectance and Raman spectroscopies are powerful techniques for the mineralogical characterization of iron ores. Reflectance spectroscopy in the visible (380–750 nm) and infrared (750–14,000 nm) parts of the electromagnetic spectrum provides mineralogical and compositional data on iron ore minerals, such as hematite and goethite, and gangue minerals, such as carbonates,

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.
