Iron Ore Roasting

Iron Ore Roasting

Iron ore can be subjected to a magnetizing roast, which is usually reductive and converts iron oxides into the magnetic form for subsequent enrichment this process is carried out in reverberatory kilns, shaft furnaces, or fluidized bed furnaces. Oxidative roasting is used to remove sulfur, carbon dioxide from carbonates, and moisture from hydrates.
