摘　　要：某进口含砷金精矿含金20 g/t、银50 g/t、铜0.15%、铅1.3%、砷8%、硫25%、炭0.35%,是典型的难处理复杂金精矿,采用焙烧、酸浸出、磨矿、氰化后金回收率不理想。按比例搭配其他精矿后再进行试验,金回收率提升明显。结果表明:在不改变试验条件的前提下,可以通过搭配其他精矿的方式,达到氰渣中金含量下降的效果,为提高成分复杂的含砷金精矿中金的回收率提供了一个新的尝试方向。An imported arsenic-containing gold concentrate contains 20 g/t gold,50 g/t silver,0.15%copper,1.3%lead,8%arsenic,25%sulfur and 0.35%carbon,which is a typical difficult-to-treat complex gold concentrate,and the gold recovery rate after roasting,acid leaching,grinding and cyanide is not ideal.After the trial was carried out in proportion to other concentrates,the gold recovery rate increased significantly.The results show that under the premise of unchanged test conditions,the gold content in the obtained cyanide slag is significantly reduced by combining suitable concentrates,which provides a new attempt to improve the recovery rate of gold in arsenic-containing gold concentrates with complex composition.
