位于个旧市南部的卡房矿田大白岩铜锡矿是个旧地区重要的铜矿产出地段,共伴生锡、金、银、钨、铋等有益组分。通过光薄片鉴定、电子探针测试和人工重砂分析发现,大白岩铜锡矿铜主要赋存状态为黄铜矿,其次为银黝铜矿和黝锡矿;锡主要以锡石,黝锡矿形式存在;伴生组分钨主要为白钨矿,铋元素以辉铋矿和自然铋存在,硫主要为磁黄铁矿、黄铁矿,其次为黄铜矿等硫化物,磁黄铁矿和黄铜矿中含有微量金。
The Dapingyan copper-tin mine, located in the southern part of Gejiu City, is an important copper mine production area in the old area with associated beneficial components such as tin, gold, silver, tungsten and bismuth. The results of optical flake identification, electronic probe test and artificial heavy sand analysis showed that the main occurrence state of copper in the Dabaiyan copper-tin ore is chalcopyrite, followed by silver tetrahedrite and stannous tin deposits. The tin mainly consists of cassiterite and stannous The tungsten is mainly associated with scheelite, while the bismuth is present as bismuthinite and natural bismuth. The major sulfides are pyrrhotite and pyrite, followed by chalcopyrite and other pyrites. Pyrrhotite And chalcopyrite contains trace gold.
