Title: Research on Iron Increase and Dephosphorization of Refractory High-phosphorus Hematite-limonite Ore
Abstract: Hematite and limonite are the dominant iron minerals in a Yunnan iron ore.As the phosphorus content amounts 0.586%,the iron ore belongs to a high-phosphorous refractory one,which can not be satisfactorily processed by conventional method.A processing flowsheet,comprising reduction roasting,magnetic separation and reverse flotation,was introduced to treat the ore,and an iron concentrate with an iron grade of 61.72%,a reduced phosphorus content of 0.20%,and an iron recovery of 67.48% can be obtained.It brings forth a novel solution for the exploitation and utilization of analogous high-phosphorus hematite-limonite ore resources.
