High Phosphorus Oolitic Hematite iron ore dephosphorization technology: China's proven reserves of high-phosphorus iron ore up to several hundred tons, the potential economic value of US $ 1 trillion. High-phosphorus iron ore has the following characteristics: (1) High grade. Generally it is above 45%. (2) The size of the inlay is fine and complicated to handle. On the microscopic surface of the microscope, the hematite granules are more than 80% below 40 microns. (3) High phosphorus content. Phosphorus is above 0.5. Traditional treatment methods include physical beneficiation , chemical beneficiation, smelting dephosphorization, magnetization roasting and biological dephosphorization. Chemical beneficiation, smelting dephosphorization and magnetization roasting have problems of high production cost and environmental pollution. Biological dephosphorization is still in laboratory research. Stage; physical beneficiation, low energy consumption, low cost, but the grade of iron concentrate is not high, and the phosphorus content of harmful impurities is high. This institute has a high-phosphorus iron ore mine in Yunnan. The ore contains 1.2% phosphorus, 42.5% iron and 12.3% silicon. The reverse flotation test has been carried out and the following indicators have been obtained: 60% iron fine powder and 0.10 phosphorus. %, the recovery rate is 80%.
