processes and purification of iron ore locally

Iron ores always contain some additional gangue. The type and amount depend on the iron ore itself and the beneficiation process. Typical remaining oxides are SiO 2, CaO, MgO, and Al 2 O 3. Wang and Sohn 43 investigated the effect of CaO and SiO 2 on swelling and iron whisker formation during the reduction of iron oxide compacts.
