摘　　要：对攀西地区某难选铁矿进行了工艺矿物学研究及选矿试验,确定了选矿工艺流程。试验表明,采用焙烧磁选反浮选降磷的工艺可以得到铁品位为60.89%、含磷0.222%的合格铁精矿,且回收率可达到72.74%。The process mineralogical investigation and processing experiment of a refractory iron ore in Panxi area, Sichuan province were carried out, and the mineral processing flowsheet was determined. The experiment showed that iron concentrate with Fe content of 60.89% and phosphorus content of 0. 222% can be obtained by roasting, magnetic separation and reverse floata- tion, and iron recovery was up to 72.74%.
