Beneficiation Of Oolitic Iron Ore

Beneficiation of Oolitic Iron Ores - Hatch

15-06-2021  Accordingly, Hatch and Ironstone are developing a new pyrometallurgical process (Hatch Ironstone Chloride Segregation) to produce metallic iron from high silica and high phosphorus oolitic iron ores. Following the chloride segregation process, the treated ore is subjected to fine grinding. The iron is then separated by magnetic separation.
