| 摘 要： | 利用矿物解离分析仪（MLA）系统等综合手段对贵州泥堡金尾矿进行工艺矿物学分析，考察了该尾矿的矿物组成、含金矿物的嵌布粒度及嵌布特征。结果表明：泥堡金尾矿中的金多以类质同象晶格态赋存于黄铁矿、氧化后的黄铁矿、赤铁矿之中，这三种金属矿物嵌布粒度微细，且均存在着复杂的连生及包裹关系。推荐采用非氰化浸出工艺处理该金尾矿

| Abstract: | The process mineralogy of Nibao gold tailings in Guizhou Province was analyzed by means of the mineral liberation analyzer (MLA) system. The mineral composition, size and distribution characteristics of gold-bearing minerals were investigated. The results show that most of the gold in Nibao gold tailings occurs in pyrite, oxidized pyrite and hematite in isomorphic lattice state. These three metal minerals are fine-grained and have complex intergrowth and encapsulation relationship. Non-cyanide leaching process is recommended to treat the gold tailings. |
