摘要 云南某铜铅锌多金属硫化矿铜品位0.45%、铅品位3.18%、锌品位4.21%,含银30.10 g/t,有用矿物以黄铜矿、闪锌矿、方铅矿等为主。黄铜矿与闪锌矿相互交代连生或混染包裹,铜、锌矿物粒度粗细不均。85.11%的铜以原生硫化铜的形式存在,铅、锌也均主要赋存于硫化矿中。浮选试验结果表明,在磨矿细度-0.074 mm 80%的条件下,以CaO+Na2S+Na2SO3+ZnSO4作调整剂、异丙基黄药作捕收剂、730A作起泡剂,1粗3精2扫铜铅混合闭路浮选可获得产率650%,铜品位5,20%、铅品位43.64%,铜回收率75.11% 、铅回收率93.00%的铜铅混合精矿;铜铅混合尾矿以CuSO4作活化剂、丁基黄药作捕收剂经1粗2精2扫闭路流程选锌可获得产率7.60%、品位46.94%、回收率85.76%的锌精矿;铜铅混合精矿经1粗1精分离浮选可获得品位42.23%、回收率8638%的铅精矿和品位27.65%、回收率61.88%的铜精矿;铜、铅、锌精矿指标均达到相应的产品质量标准,并综合回收了银。试验结果可为该矿石的开发利用提供技术参考。

Abstract: Some polymetallic sulfide ores in yunnan has copper grade of 0.45%,lead grade of 3.18% and zinc grade of 4.21%,containing 30.10 g/t silver,The useful minerals are mainly chalcopyrite,sphalerite and galena。Chalcopyrite and sphalerite are metasomatic or mixed—dyed,with uneven grain size.85.11% copper exists in the form of primary copper sulfide,lead and zinc ores also occur in sulfide ores。 The flotation test results show that under the condition of grinding fineness -0.074 mm 80%,CaO+Na2S+Na2SO3+ZnSO4 as the adjusting agent,isopropyl xanthate as the collector,730A as the foaming agent,the mixed closed—circuit flotation of 1 crude,3 fine and 2 scavenging copper and lead can obtain a copper and lead mixed concentrate with yield of 6.50%,copper grade of 5.20%,lead grade of 43.64%,copper recovery rate of 75.11% and lead recovery rate of 93.00%.The zinc concentrate with yield 7.60%,grade 46.94% and recovery 85.76% can be obtained by using CuSO4 as activator and butyl xanthate as collector 1crude,2fine and2 scavenging closed circuit cleaning process.lead concentrate with grade 42.23%,recovery 86.38% and The copper concentrate grade 27.65%, recovery 61.88% can be obtained by 1 coarse and 1 fine separation and flotation of the copper and lead mixed concentrate.Copper,lead and zinc concentrate reached the corresponding quality standards,and silver was recovered.The test results can provide technical reference for the development and utilization of the ore.
