Systematic process mineralogy study on hornstone copper-molybdenum ore in Jiama,Tibet,is carried out by the use of microscope,MLA,electronic probe and chemical analysis,investigates the mineral composition,mineral embedding characteristics,ore structure,target mineral type and distribution rate in ores,and discusses the mineralogical factors that influence target mineral recovery from ores.The results show that the relative sulfide content in ores is 4.48 %;the gangue minerals are mainly quartz,feldspar and mica group;copper minerals are mainly chalcopyrite dominated by -0.053 mm grains,and the chalcopyrite closely related to gangue minerals is easily lost,influencing copper recovery;molybdenum minerals are mainly molybdenite dominated by -0.053-+0.010 mm grains,poor locked molybdenite and gangue minerals are easily lost into flotation tailings.The research results provide basis for efficient development and utilization of the ore resource.
