恩施渔塘坝硒矿床中硒的赋存状态研究

Study on the Occurrence of Selenium in Yutangba of Enshi

通过光学显微镜、电子探针等手段研究查明恩施渔塘坝硒矿床矿石特征及硒的赋存状态,主要查明硒的两种赋存状态:一种为硒的独立矿物,即自然硒、方硒铜矿;另一种以类质同像的形式存在,即含硒黄铁矿、含硒铜蓝和含硒黄铜矿。

The authors find out selenium ore characteristics and the occurrence of selenium in Yutangba of Enshi by methods of optical microscopy and electron probe microanalysis（ EDX） etc.It is found out that the two species of selenium,a kind of independent selenium minerals： native selenium and selenium copper,and the other is se-bearing minerals：Se-bearing pyrite,Se-bearing covellite and Se-bearing chalcopyrite.
