Study of Ti Occurence in An Low-grade Iron Ore

The occurence condition of a low-grade iron deposit in northwestern Guizhou are detail studied which the EPMA is the main research technique combine with conventional chemical analyses,chemical phase analyses and intramodal distortion microscope study.The iron in ore existed mainly in the form of limonite and few is hematite.Gold bearing mineral and clay mineral usually appears mixed,uneven distributes,the lump sizes are different and the dissemination between minerals is complex.Titanium in ore,one is mixed distributes with vein mineral as independent mineral rutile,anatase and ilmenite,another is residual titanium in limonite after alteration.By the study based on the Fe and Ti occurence character,the suggestions of iron and titanium mineral pre-enrichment by dispersion-flocculation-magnetic separation and iron and titanium dispersion by direct-reduction process.
