摘要
雄龙西金矿床位于甘孜-理塘断裂带内,矿石类型为构造蚀变岩型,金平均品位为8.36×10-6。矿石矿物主要有毒砂、黄铁矿、黄铜矿、闪锌矿、黝铜矿、辉砷镍矿、金红石,自然金、硫钴矿偶见;金矿物以微细粒金形式产出,金赋存状态以包裹金为主(占89.67%),其次为粒间金,载金矿物主要为黄铁矿、毒砂。在分析雄龙西金矿石特征的基础上,提出浮选工艺流程。经试验,获得金品位为112.0×10-6、砷含量为11.94%的金精矿,产率为7.12%,金回收率达到95.13%,选矿试验效果显著。
Xionglongxi gold deposit is localed in Ganzi-Litang fault zone.The ore is a structural altered rock type with an average gold grade of 8.36×10-6.Ore minerals are mainly arsenopyrite,pyrite,chalcopyrite,sphalerite,tetrahedrite,gersdorffite,rutile,and occasionally natural gold and linnaeite.Gold minerals are produced in the form of fine-grained gold.The occurrence is dominated by inclusion gold(accounting to 89.67%),and some intergranular gold.The gold-bearing minerals are mainly pyrite and arsenopyrite.Based on the research of ore characteristics of Xionglongxi gold deposit,the flotation process was put forward.The gold concentrates with 112.0×10-6 gold grade and 11.94%arsenic content was obtained by experiment.The yield is 7.12%,the gold recovery rate is 95.13%,and the effect of beneficiating ore test is significant.
