应用煤基直接还原—磁选—氰化提金工艺处理某铁帽型含金矿石，解决了矿石中铁、金分离问题。结果表明，采用该工艺可获得优质海绵铁；含金磁选尾矿经浮选碳后金氰化浸出率达９８．６１％。
Application of coal-based direct reduction - magnetic separation - cyanide gold extraction process of a cap-type gold-bearing ore, to solve the iron ore, gold separation problem. The results show that high quality spongy iron can be obtained by this process. The gold cyanide leaching rate reaches 98.61% after flotation of carbon containing tailings.
