甘肃某难处理金矿预处理-氰化试验研究

Experimental Study on Pretreatment-cyanide of a Refractory Gold Ore in Gansu Province

甘肃某难处理金精矿的直接氰化浸出率为55%~59%,对该金精矿进行预处理-氰化试验研究,试验结果表明:难处理金精矿进行预处理可将载金矿物分解,使金充分暴露出来,并将有害物质分解去除或改变其性质,消除其对浸金过程的不利影响,大大提高金的浸出率。

Research on the pretreatment-cyanide for the gold concentrate in Gansu whose leaching rate is55-59%.The test results show that the pre-treatment of the refractory gold concentrate can be onthegold loaded mineraldecomposition, making gold fully exposed, making the harmful substance decomposition to remove or change thenature and eliminate the adverse effects on the process of gold leaching in, greatly improving the leaching rate of gold.
