dephosphorization of high phosphorus manganese ores Production of (Mn,Fe)-Carbide Containing Low Phosphorus . The dephosphorization process for high phosphorus iron ores have recently been studied employing several methods. Novel method for iron recovery from hazardous iron ore ... In this paper, a novel method to recover iron from iron ore tailing (IOT) was studied. The method was induced with carbothermic reduction, followed by magnetic flocculation separation (MFS) and conventional magnetic separation (CMS). Experimental Study on Desilication of the High-Phosphorus ... In order to promote the rational utilization of high-phosphorus iron ore in western Hubei of China, the effect of process parameters on desilication rate of the high-phosphorus hot metal was investigated. The results show that the desilication rate increases slightly with indistinctive effect with the increasing of desilication agent addition.    Read More
