摘要: 对攀西某钒钛磁铁矿深部矿石进行了系统的工艺矿物学研究,揭示了其矿物组成、主要有用矿物的嵌布特性和有价矿物的单体解离难易程度,作为制定选矿工艺流程和合理开发利用该钒钛磁铁矿资源的参考依据。采用2段磨矿3段磁选的阶段磨选选铁工艺流程可获得TFe品位为58.11%,回收率为57.65%的高质量铁精矿。但要获得此高质量铁精矿需深度细磨至-0.030 mm粒级含量为86%以上,将增加企业成本,以目前的技术条件该矿石并不适合生产高质量铁精矿。

Abstract: Systematic mineralogy research was carried out on a deep vanadium-titanium magnetic ore from west Panzhihua, which revealed its mineral composition, distribution characteristics of main minerals and difficulties to liberate of valuable minerals, and provided reference for beneficiation process selection and rational exploitation and utilization of these resources. High quality iron concentrate with iron grade of 58.11%, iron recovery of 57.65% could received by two stages of grinding-three stages of magnetic separation process, while the mesh of grinding should reach 86% passing -0.030 mm. It’s not suitable for the production of high quality iron concentrate for current technical conditions, as non-economical.
