【摘要】 利用相态分析方法 ,配合扫描电镜、X光衍射分析及红外光谱分析等测试手段 ,对某铜钴矿化区钴矿石中钴镍的赋存状态进行了研究。综合分析查定了钴镍在该铜钴矿化区的赋存状态主要有 :①钴镍以含钴的镍黄铁矿产出 ;②钴镍与铁呈类质同象状态存在于黄铁矿、黄铜矿和菱铁矿中 ;③钴镍以吸附态存在于伊利石等粘土矿物中。更多还原

【Abstract】 The occurrence states of cobalt and nickel in complex cobalt ores in a mine were studied using phase analysis procedure and by means of X ray diffraction, sweep electronic microscope and infra red techniques. The results show that the occurrence states of cobalt and nickel in the complex cobalt ores are existence as: ① cobalt-bearing pentlandite; ② isomorphism state with iron existing in pyrite, chalcopyrite, siderite; ③ adsorbed states exiting in clay minerals such as illite etc.更多还原
