本文研究认为哈海岗钨钼多金属矿床主要有三种矿化类型:脉状铜铅锌矿,细网脉状矽卡岩型钨钼矿和块状磁黄铁矿矽卡岩型钨钼矿。通过采用光学显微镜和扫描电镜技术方法对白钨矿和辉钼矿矿物学特征进行了研究:白钨矿是矿石中主要含钨矿物,WO3含量为0.228%。主要粒度范围为0.01~0.32mm,属于细-微细粒不均匀嵌布类型。钨的赋存状态查定表明,以白钨矿矿物形式存在的钨占原矿总钨的86.56%;辉钼矿Mo含量0.138%;粒度较细,粒度比较均匀,主要粒度范围为0.02~0.16mm,属于微细粒较均匀嵌布类型。钼的赋存状态查定表明,辉钼矿中的钼占原矿总钼的83.31%。属于较难选的钨钼矿石。
The study indicates that there are mainly three types of mineralization in the Hahaigang tungsten-molybdenum polymetallic deposit: vein copper-lead-zinc ore, fine-mesh vein skarn type wolframite and massive pyrrhotite skarn type tungsten-molybdenum mine . The mineralogical characteristics of scheelite and molybdenite were studied by means of optical microscopy and scanning electron microscopy: scheelite is the major tungsten mineral in the ore, with a WO3 content of 0.228%. The main particle size range of 0.01 ~ 0.32mm, belonging to the fine - fine uneven cloth embedded type. Investigation of the occurrence state of tungsten showed that the tungsten in the form of scheelite mineral accounted for 86.56% of the total tungsten in the ore and Mo content of the molybdenite was 0.138%. The grain size was fine and the grain size was relatively uniform. The main grain size ranged from 0.02 to 0.16 mm , Belonging to the more uniform micro-embedded type cloth. The investigation of the occurrence of molybdenum shows that the molybdenum molybdenum ore accounted for 83.31% of the total molybdenum ore. Tungsten molybdenum ore are more difficult to choose.
