摘要
通过试验对耗氰、耗氧较高且难浸出的金精矿的浸出工艺参数进行分析。试验结果显示 ,金的浸出不仅取决于超细磨矿 ,还必须经过强碱浸出预处理 ,并使矿浆中总氰与铜的摩尔比高于 3:1,才能降低氰耗及提高浸出率。
Through test,the gold minerals which consume too much oxygen and were difficult to leach and its technology parameters were analysed. Leaching of gold not only depends on superfining,but leaching pretreatment of strong base,and the mole ratio is above 3:1.Only this, consumption of cyanogen can be reduced and high leaching rate can also be gained.
