| Abstract: |
| Taking the complex refractory iron ore from Yunnan and western Yunnan as the research object, the mineralogy of the ore was studied by means of XRF, chemical multielement analysis and X-ray diffraction (XRD), and the sorting scheme was proposed. The results show that the element with the highest recovery value is iron, which mainly exists in the form of magnetite. Sulfide ores mainly include pyrrhotite, pyrite and sphalerite, and gangue minerals are mainly serpentine and talc. Based on the study of ore properties, it is shown that by using the beneficiation process of stage grinding stage separation-flotation sulfur removal to separate iron ore, sulfur concentrate with S grade of 21.90% and S recovery rate of 68.52% and iron concentrate with TFe grade of 61.56% and TFe recovery rate of 67.41% and S content of 0.67% are obtained. It provides support for the efficient utilization of iron ore resources. |
