摘要: 铋是一种重要的金属资源,其常伴生于复杂金属矿中,本试验的研究对象为云南省某铜铋硫化矿.对该矿物进行了化学多元素分析和矿物组成分析,原矿中含有0.14%铋,且主要赋存在辉铋矿中,具有较高的回收价值.针对该矿中的铋矿物进行了详细的浮选研究,试验结果表明,浮选可有效回收该铜铋硫化矿中的铋元素.通过一粗一扫三精的浮选闭路流程,可获得产率、品位和回收率分别为1.44%、7.13%%和73.34%的铋精矿.

Abstract: Bismuth is an important kind of metallic mineral resource and commonly occurrence in polymetallic ores.In this work,the study focused on the Cu-Bi sulfide ore in Yunnan.The sample was investigated by chemical analysis and mineral analysis.The raw ore contained 0.14% Bi and mainly occurrence inbismuthinite,which has commercial recoverable value.This work used flotation to beneficiate bismuth.The results determined that bismuth was effectively concentrated by flotation.A bisthmuth concentrate with yield of 1.44% and the grade of 7.13% with concentrate recovery 73.34% was achieved by a flowsheet of "one-stage roughing flotation,one-stage scavenging flotation and there-stage cleaning flotation".
