With increasing consumption of iron ore over the world, new technology of beneficiation and smelting is more urgently needed than ever before to explore ores which, are difficult to utilise by beneficiation and smelting processes. Oolitic Hematite mines, iron ore with poor beneficiation efficiency are widely distributed in China with the most abundant deposits. In this paper, comprehensive technology integrating beneficiation and smelting processes was proposed. This paper reports the experimental results on ore beneficiation, pretreatment of hot metal with high phosphorus and dephosphorization during direct reduction. It would provide technology support for the efficient utilization of high phosphorus Oolitic Hematite, and also provide technology for industrial demonstrating projects.
