| 摘 要： | 金矿经过氰化浸出后会产生大量的贫液,且贫液内含有各种氰化络合物及其杂质。为了查清贫液是否可以返回再利用及杂质对氰化浸出过程的影响,本文首先对贫液中的杂质种类和含量做了检测,然后在其他条件相同的基础上,通过使用新水和贫液分别进行氰化浸出试验,对两者产生的贵液和贫液中的杂质含量进行检测并记录,以及浸出时间和浸出率进行记录和计算,绘制出两者的浸出时间与浸出率关系对比曲线。试验结果表明,贫液返回再利用所产生的贵液和贫液中的杂质含量与使用新水时的基本相同,对氰化浸出生产危害不大,在一定条件下浸出率还略高于使用新水,因此,贫液可以返回再利用。

| Abstract: | Large quantity of cyanide barren solution is produced during the process of glod cyanide leaching,which contains many kinds of cyanide complexes and impurities.Whether the barren solution could be recycled or not is unknown.To investigate the influence of impurities on the process of cyanide leaching,the type and content of the impurities were determined first.Then under the same condition except the difference of fresh water and barren solution,the test of cyanide leaching was carried on.The impurity content in the barren and pregnante solution was written down.At the same time,the leaching time and the leaching rate were accounted and their relation curve was drawn.The test results show that the impurity content in the barren and pregante solution produced from the barren solution reuse is almost the same as that from the fresh water,which does no harm to the production of cyanide leaching.Furthermore,under certain condition the leaching reaching is slightly higher than that by using fresh water.Therefore,the barren solution can be returned to be reused. |
