| 摘 要： | 哈西亚图铁多金属矿床中共生的金矿规模已达中型,可大大提高该矿床的经济效益,对金矿综合回收利用方法的研究显得尤为重要。矿石工艺类型为中硫化物矽卡岩型金矿石,矿石自然类型属混合矿。矿石中主要金属矿物为磁铁矿、磁黄铁矿和黄铁矿,贵金属矿物为自然金和银金矿。通过试验研究,浮选工艺推荐＂浮选金—尾矿磁选铁—铁精矿浮硫＂方案,浸出工艺推荐＂全泥氰化炭浸提金—尾渣磁选铁—铁精矿浮硫＂方案。试验结果表明,采用全泥氰化炭浸—磁选铁（浮选除硫）工艺处理哈西亚图金矿石效果最佳。

| Abstract: | The gold ore associated in Haxiyatu iron-polymetallic deposit has reached medium-scale,which can greatly improve the economic efficiency of the iron-polymetallic deposit.Research on comprehensive recovery and utilization method of gold ore is very important.The gold ore belongs to the sulfide skarn type,with the natural type belonging to the mixed ore.The metal minerals in the ore are dominated by magnetite,pyrrhotite and pyrite,and noble metal minerals are native gold and electrum.Through the experiment,the flotation process scheme is recommended that“gold flotation,tailings magnetic iron and iron concentrate flotation sulfur”.Leaching process scheme is recommended that“all sliming cyanidation carbon leaching,tailings magnetic separation iron and iron concentrate flotation sulfur”.According to the test results,the process by all sliming cyanidation carbon leaching and magnetic iron（remove sulfur by floating） can obtain better effect. |
