Abstract

In this study, mineral structures and compositions of Peru raw ore (PRO) were investigated by optical microscope, scanning electron microscope and X-ray diffraction. The results show that PRO is primarily composed of magnetite, haematite, gangue and sulphide. A small amount of chalcopyrite and calcium phosphate also exist in PRO. Gangues are mainly quartz minerals. Sulphides exist as FeS, Fe2S3 and FeS2, respectively. Sulphides, most of which accrete with gangues, are embedded among ferrous bodies in the form of banding, schistose, or porphyritic structures. The particle sizes of sulphides and gangues are between 200 and 500 μm. Some of them are over 1000 μm. It can be concluded that high liberation degree of sulphides and gangues will be obtained after crushing. After flotation and magnetic separation in Shougang Jingtang dressing plant, the Fe content of PRO was improved from 56.68 to 65.75%. The sulphur content dropped to 0.48% from 3.44%.
