我矿矿床为矽卡岩磁黄铁矿含铜型多金属硫化矿矿床。主要金属矿物有黄铜矿、方黄铜矿、磁黄铁矿、黄铁矿、白钨矿、自然铋、锡石、绿柱石等;脉石矿物是透辉石、透闪石、柘榴子石、阳起石、电气石、石英、方解石等。原矿含铋0.08～0.11％。98％以上的铋呈自然铋形态存在,它以细粒散点状、片状赋存于铜铁硫化矿物的复杂浸染体中,嵌布粒度绝大多数小于0.05毫米。
The mine is a skarn pyrrhotite copper-bearing polymetallic sulphide ore deposit. The main metal minerals are chalcopyrite, side chalcopyrite, pyrrhotite, pyrite, scheelite, natural bismuth, cassiterite, beryl etc .; gangue minerals are diopside, tremolite, grenadier Stone, Yang stone, tourmaline, quartz, calcite and so on. Ore bismuth containing 0.08 ~ 0.11%. More than 98% of bismuth exists in the form of natural bismuth, which is in the form of fine particles scattered and flaky in the complex dipping body of copper-iron sulphide minerals. The majority of the dislocations are less than 0.05 mm in size.
