摘要: 本文以湖南某铜矿为研究对象,针对该矿矿石性质,采用单一浮选的工艺流程选别该矿石。在条件试验的基 础上进行了小型闭路试验,获得了铜品位为26.15%的合格铜精矿,铜的回收率为90.75%,铜精矿含银89.68g/t,达到综合回收的目的, 获得了比较好的选矿指标。Abstract: A copper ore in Hunan province was taken as the research object. In view of theore ore properties, the single flotation process was adopted. On the basis of the condition test, the small closed-circuit experiment was conducted ,obtaining the qualified copper concentrate with the copper grade of 26.15% and thecopper recovery of 90.75% and containing 89.68 g/t of silver, achieving the goal of comprehensive recovery. Good beneficiation indexes were obtained.
