• Increasing Iron and Reducing Phosphorus Grades of Magnetic ...

    Highphosphorus oolitic iron ore, treated by suspended flash magnetic roasting, contained % iron (mainly present as magnetite) and % phosphorus (present as collophane). Lowintensity magnetic separation (LIMS) was combined with reverse flotation to increase the iron and reduce the phosphorus contents of the roasted product. The results showed that an optimized iron ore concentrate ...
