摘要： 为了改进铜阳极泥中提取贵金属的工艺，采用XRD，SEM和显微镜的方法对阳极泥进行了工艺矿物学研究.研究结果表明，阳极泥中颗粒粒度<38μm占7853%，38~45μm占935%，>45μm占1212%；主要元素为Ni，Cu，Se，Ag，Au；主要物相有金及其合金、银及其化合物、铜及其化合物、氧化镍、硫酸钡和黄铁矿等；金和银是主要贵金属，个别小颗粒金为金铅合金，银以硒化银和铜银硒的形式存在；铜和镍是主要贱金属:铜为单质铜、硫酸铜、硒化铜以及铜银硒，镍主要为氧化镍；铜阳极泥以硫酸铜为基底，氧化镍中经常包裹有单质铜.

Abstract: In order to improve the technology of extracting noble metals from the copper anode slime， the technological mineralogy investigation of the anode slime was studied by XRD， SEM and optical microscope. The results showed that the particle size in the anode slime which was less than 38μm accounted for 7853%， the particle size ranged from 38 to 45μm accounted for 935%， and that of more than 45μm accounted for 1212%. The main elements were Ni， Cu， Se， Ag， Au. The main phases were gold and its alloys， silver and its compounds， copper and its compounds， nickel oxide， barium sulfate， and pyrite etc.. The gold and silver were major noble metals， individual small particles of gold was aurum lead alloy， and silver existed in forms of silver selenide and eukairite. Copper and nickel were major base metals， copper existed in native copper， copper sulphate， copper selenide and eukairite. Nickel was mainly nickel oxide. The anode slime of the copper was formed with copper sulphate as the matrix， and the native copper often coated with the nickel oxide.
