Hunan the Guiyang Huangshaping multi - metal mine is one of the Shonan 's representative deposit . It is an important base for the production of lead and zinc , and is rich in silver , copper , iron , tungsten , tin , molybdenum , bismuth and other mineral resources . This article by field survey sampling and the indoor chemical analysis , optical microscopy, scanning electron microscopy spectroscopy analysis and X -ray diffraction phase analysis and other means to identify the type of molybdenum tungsten tin bismuth ores in the mine process , chemical composition, mineral composition , structures and processes mineralogical characteristics of the ore minerals scheelite natural bismuth, bismuthinite , molybdenite , pyrite , magnetite . Gangue mineral andradite , hedenbergite , diopside , fluorite , calcite , wollastonite . The ore , tungsten, molybdenum, bismuth tend to concentrate in the fine fraction , -200 mesh fractions of tungsten, molybdenum, bismuth share of each of 54% , 57 %, 80% . Grinding fineness accounted for 75% -200 mesh , tungsten , molybdenum , bismuth minerals monomer solution off ( or ideal recovery) of 78% , 78% , 74% , respectively , that the south of this area skarn ore of tungsten , molybdenum , bismuth has good prospects of comprehensive utilization . Tin independent minerals - cassiterite is rare in this area , and was fine spherical particles of magnetite is closely connected to students unable to monomer dissociation , it is of little value , the use of tin under the existing conditions .
