| 摘 要： | 针对某矿山含碲金矿原矿和碱浸预处理后样品，进行了工艺矿物学检测，分别明确了样品中矿石的元素成分、矿物组成及矿物嵌布特征、目标元素赋存状态、目标矿物的粒度分布等情况。研究结果表明，原矿中存在碲金矿，在浸出过程中影响金的浸出率；通过碱浸预处理工艺可将碲金矿氧化，改善金的浸出效果；原矿中细粒级矿物在碱浸过程中被氧化分解为微细粒矿物；碱浸过程中黄铁矿和碲金矿被氧化释放了其中金矿物。说明碱浸对碲金矿预处理效果明显，对含碲金矿石工艺流程的制定具有指导意义。

| Abstract: | This article was aimed at a certain tellurium-bearing gold ore and its samples after alkaline leaching. Through the process mineralogical analysis of two samples, the elemental composition, mineral composition and minerals of the ore in the sampleswere respectively determined. The characteristics of the embedding, the occurrence state of the target element, the particle size distribution of the target mineral, etc. were reported. The research results showed that the presence of tellurium-bearing gold ore in the raw ore affectedthe leaching rate of gold during the leaching process. The alkaline leaching pretreatment process can oxidize the tellurium-bearing gold ore; the fine-grained minerals in the raw ore were oxidized and decomposed into fine particles during the alkaline leaching process. Granular minerals,during the alkaline leaching process, pyrite and tellurium-bearing gold ore were oxidized to release gold minerals. It is shown that the alkaline leaching pretreatment process has obvious effects on the treatment of tellurium-bearing gold ore, and has guiding significance for the formulation of the process flow of tellurium-bearing gold ore. |
