| 摘 要： | 针对西北某含金氧化矿中自然金多赋存在褐铁矿矿物微裂隙中,少量嵌布在石英或黄铁矿晶粒中,嵌布粒度细等特点,试验分别进行浮选和全泥氰化浸出方案对比。试验结果表明,采用浮选法金回收率仅38.38%,不能有效回收该矿石中自然金。采用氰化浸出法,金浸出率为77.03%,较好的实现了该含金氧化矿中金的高效回收。

Experimental Study on Gold Recovery from Gold-bearing Oxide Minerals |
| |
| Abstract: | Due to natural gold occurs primarily in the micro cracks of limonite, with a few occurrence of fine dissemination embedded in pyrite and quartz, it becomes hard to recover for a certain gold bearing oxide ore in Northwest.Experiments were carried out to compare the flotation process with the complete mud cyaniding schemes.The results showed that the flo-tation method could not effectively recovery gold from this minerals and gold recovery was only 38.38%.Whereas by using the complete mud cyaniding method, gold Leaching rate was 77.03%, better realizing the efficient recovery of gold from this gold-bearing oxide minerals. |
