摘要

摘要: 某低品位钒钛磁铁矿含TFe 17.92%,含TiO₂ 6.19%,采用干式预选抛尾—阶段磨矿阶段选别工艺后,获得了TFe品位60.57%、全流程铁回收率49.34%的铁精矿,铁精矿中含TiO₂ 7.89%。在选铁过程中,经过干式粗粒抛尾以后,铁、钛、钒、铬、钪、钴、镍等元素皆主要在粗抛精矿中富集;经过湿式磁选以后,铁精矿中钒、铬得到了较好的富集,钴、镍有一定程度的富集,而钪主要富集在弱磁选尾矿中,硫在干式尾矿中含量较低,在铁精矿中有一定程度富集。

Abstract: A low grade vanadium-titanium magnetite contains 17.92% of TFe（total Fe） and 6.19% of TiO₂.Using the process of tailings discarding by dry pre-concentration followed with staged grinding and concentration,an iron concentrate containing 60.57% of TFe and 7.89% of TiO₂ can be obtained,and recovery rate of Fe in the whole process is 49.34%.After tailings discarding at a coarser size,Fe,V,Ti,Cr,Sc,Co and Ni are mainly concentrated in the primary concentrate.Through wet magnetic separation,V and Cr in the iron concentrate are enriched apparently,while Co and Ni are concentrated in some degree,with Sc mainly in the weak magnetic separation tailings.S in the dry tailings is of low content but is enriched in the iron concentrate to a certain extent.
