中文摘要: 某含铜矿石采用全泥氰化浸出工艺回收金，金浸出率仅为88.21%、铜浸出率高达19%左右。为减少铜矿物溶解对氰化浸出过程的影响，提出了“控制氰根离子浓度减弱铜溶解”的技术思路，并通过分点添加氰化钠的方式来控制氰根离子浓度。工业应用结果表明，在不大范围改变原工艺流程的基础上，铜浸出率可有效降至1.93%，金浸出率提高至93.40%。
Abstract:Gold leaching rate of copper-bearing gold ore by cyanide leaching was only 88.21% due to dissolution of copper minerals, whose leaching rate is about 19%. In order to reduce effect of dissolution of copper minerals on cyanidation leaching, a novel technology to weaken copper minerals dissolution by “carefully controlling concentrations of dissociative cyanide ions” was put forward. Concentrations of dissociative cyanide ions were controlled by fractional adding of sodium cyanide. Industry application results show that copper leaching rate drops to 1.93% and gold leaching rate significantly rises to 93.40% without a big change of original technological process.
