云南某低铜贫铁矿石选铜试验

云南某低铜贫铁矿石铜含量为0.35%、铁含量为19.22%,91.43%的铜为硫化铜。对该矿石中铜的选矿工艺进行了研究。结果表明,矿石在磨矿细度为-200目占80%的情况下,以TX-31为浮铜捕收剂,经1粗2扫3精、中矿顺序返回流程处理,获得了铜品位和铜回收率分别为22.48%和91.20%的铜精矿,较好地实现了铜的回收,选铜铁损失率仅为2.18%,为后续选铁创造了条件。

Copper Separation from a Low Copper Grade and Lean Iron Ore from Yunnan

There is 0.35％ Cu,19.22％ Fe in a low copper grade and lean iron ore,91.43％ Cu in form of copper sulfide.Mineral processing technology of copper was studied on the ore.The results show that copper concentrate with copper grade of 22.48％ and recovery of 91.20％ was obtained,under condition of ore grinding fineness of-200 mesh 80％,with TX-31 as copper flotation collector,by one roughing,three cleaning,two scavenging,and middling sequential return process.Well recovery of copper was realized,and loss rate of iron in copper separation is only 2.18％,created a condition for the subsequent selection of iron.
