湖南第四矿重选的粗精矿,金属矿物主要有黑鎢矿、白鎢矿、黃銅矿、錫石、黝錫矿等,并有少量石英、方解石、螢石和长石等脉石矿物。矿物組成复杂,互相关系极为密切。常見石英、黃銅矿、白鎢矿等沿黑鎢矿解理或断裂面充填与交替,有时也見到黑鎢矿被白鎢矿交替呈假象。据矿物鑑定結果:粒度在0.074毫米以下,黑鎢矿中仍有网状或星点状的黄銅矿嵌布,白鎢也普遍呈网状、点状
Hunan ore concentrate re-election of the fourth mine, the main metal minerals are scheelite, scheelite, chalcopyrite, cassiterite, stannous tin, and a small amount of quartz, calcite, fluorite and feldspar and other gangue minerals . Complex composition of minerals, closely related to each other. Common quartz, chalcopyrite, scheelite and other wolframite cleavage or fracture surface filling and alternating, and sometimes also saw Wolframite was scheelite alternation was illusion. According to the results of mineral identification: particle size below 0.074 mm, wolframite mesh or star-like chalcopyrite embedded, white tungsten is also generally reticular, punctate
