摘要
采用两段铜硫混合浮选-粗精矿再磨-铜硫分离工艺对某高海拔铜矿进行了选矿工艺优化试验研究。两段铜硫混合浮选采用异步浮选方法,使用对铜选择性好的KMY-1铜捕收剂进行铜硫分离,可高效回收微细粒级嵌布难选铜矿物。小型闭路试验获得了铜品位23.06%、铜回收率78.29%的铜精矿,比现场生产流程得到的铜精矿铜品位和铜回收率分别提高了2.92百分点和9.59百分点。
A beneficiation flowsheet comprised of two stages of roughing for copper-sulfur bulk flotation,bulk concentrate regrinding and Cu/S separation was adopted for optimization of beneficiation technique for a high-altitude copper ore.By applying asynchronous flotation for Cu-S bulk flotation and using KMY-1,a copper collector with good selectivity for Cu/S separation,efficient recovery of refractory copper minerals with microfine-grained dissemination can be actualized.A laboratory closed-circuit test finally produced a copper concentrate grading 23.06%Cu at 78.29%recovery,up by 2.92 percentage points and 9.59 percentage points correspondingly compared to the copper concentrate yielded from the on-site processing flow.
