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. By the study based on the Fe and Ti occurence character, the suggestions of iron and titanium mineral preenrichment by dispersion -flocculation -magnetic separation and iron and titanium dispersion by direct- reduction process.
