摘要
某复杂铜硫矿含铜0.710%、含硫8.110%、含钼0.021%,具有硫铜比高、含次生铜、伴生钼含量低、铜硫嵌布特征复杂等特点。为高效开发利用该资源,通过工艺矿物学研究,查明矿石矿物特性,开展了详细的选矿试验研究,进行了“异步浮选-合并精选”与“异步浮选-分别精选”的浮选工艺流程对比研究。“异步浮选-合并精选”工艺可获得铜精矿含铜23.82%,含钼0.31%,铜回收率为91.50%,钼回收率为38.25%;“异步浮选-分别精选”工艺可获得总铜精矿含铜23.98%、含钼0.52%,铜回收率为91.74%、钼回收率63.19%。推荐采用“异步浮选-分别精选”工艺处理该矿石。
A complex copper-pyrite ore contains 0.710%Cu,8.110%S,and 0.021%Mo.It has the characteristics of high sulfur-to-copper ratio,secondary copper-containing,low content of accompanying molybdenum,and complex copper-sulfur dissemination.In order to efficiently develop and utilize this resource,the mineral characteristics of the ore is find out by the process mineralogy research,and then the detailed beneficiation test is carried out,a comparative study of“asynchronous flotation-combined selection”flotation process and“asynchronous flotation-separate selection”flotation process is carried out.The flotation process“asynchronous flotation-combined selection”could obtain copper concentrate containing 23.82%Cu and 0.31%Mo with the copper recovery of 91.50%,and molybdenum recovery of 38.25%.The flotation process“Asynchronous flotation-separate selection”could obtain copper concentrate containing 23.98%Cu and 0.52%Mo with the copper recovery of 91.74%,and molybdenum recovery of 63.19%.The“asynchronous flotation-separate selection process”is recommended to treat this ore.
