摘　　要：新疆某金矿位于北准噶尔成矿带卡拉麦里成矿亚带,金成矿地质条件优越。其原生矿石由于碳、砷、锑含量较高,且易泥化,属较难选矿石。在实验室中原生矿采用制粒浸出,直接浸出率仅为16.99%,但原生矿采用浮选精矿焙烧-氰化工艺,金总回收率可达73.14%。本次实验结果表明,采用选冶联合工艺流程,可以在合理的成本范围内使该金矿达到较高的选冶指标。The gold deposit in Xinjiang is located in the Kalamailimetallogenic subzone of the northern Junggarmetallogenic belt,with superior geological conditions for gold mineralization.The primary ore is difficult to separate due to its high carbon,arsenic and antimony contents and easy mudding.In the laboratory experiment,the primary ore is leached by granulationand the direct leaching rate is only 16.99%.However,by adopting flotation concentrate-roasting-cyanidation process,a total gold recovery of 73.14% is achieved.The study results show that the combined beneficiation and metallurgy process can make the gold mine reach a higher beneficiation and metallurgy index at areasonable cost.
