Method for comprehensively treating phosphorus-containing oolitic hematite and red mud

The present invention discloses one phosphorus Oolitic and integrated approach to the red mud, wherein: the Oolitic ore, red mud, according to a certain proportion mixing coal crushing, mixing; crushing reduction roasting of metal; calcine by slow cooling to 400 ~ 750 ℃ ​​after quenching water quench, water quench calcine ball; milling slurry magnetic separation based sponge iron powders and the tailings; based on the melting sponge iron powders containing phosphorus less than 0.01 % quality hot metal. The method of the present invention, the process is short, continuous, energy-saving, large capacity, high resource utilization, environmentally friendly; solve the red mud stockpiling construction cost and maintenance cost is high, the product can be used as high-quality steel-making raw materials, products high value.
