| Abstract: |
| For efficient utilization (2702meters) lead-zinc mineral resources of Xitieshan deep ore body (-2702meters),In view of the technological mineralogy has important guiding effect to flotation performance research of ore.The detailed study of technological mineralogy was investigated by X-ray fluorescence spectrometer, X-ray diffraction analyzer and microscope test ,etc. The flotation behavior of lead-zinc ore was also investigated. The results indicate that the main metallic minerals in ore were pyrite, sphalerite, galena and a small amount of magnetite, limonite, chalcopyrite, sphalerite and pyrrhotite,etal. Moreover,the valuable minerals for lead, zinc, sulfur, and associated gold ,silver can be comprehensive recovery. The gangue minerals were in the majority with diopside, followed by quartz, calcite, chlorite, hornblende. Respectively ,the galena and sphalerite was medium fine and medium grained disseminated features, Most of the useful minerals disseminated extent above 0.074 mm, which in favour of mineral dissociation. The flotation test results show that It can realize the efficient recovery of main metal lead and zinc in the ore under the coarser grinding fineness, The ideal beneficiation comprehensive index can be obtained by the existing production process, the results provides the technical basis for the beneficiation production of deep ore at production field. |
