| 摘 要： | 变质岩型金矿用常规的浮选方法提金，难以取得良好的回收效果，采用工艺矿物学研究方法，查明了金在矿石中的赋存状态和嵌布特征，研究结果表明，金以自然金的形式嵌镶于脉石粒间或脉石与磁黄铁矿粒间，基于此研究制定出了合适的选矿工艺流程，取得了最佳的回收效果。

| Abstract: | It is difficult to get a good recovery in gold extraction from the metamorphosed rock-type gold mines by conventional flotation.By means of the process mineralogical method,the occurrence state and the distribution feature of gold in the ore has been investigated.Results show that gold is,in the form of natural gold,setting between gangue particles or between gangue and pyrrhotite particles.On the basis of this result,a suitable gold extraction process has been worked out and the optimum recovery has been obtained. |
