摘要
针对刚果(金)Kamoa铜矿石中铜矿物嵌布粒度粗细极不均匀、嵌布关系复杂的特点,采用阶段磨选工艺进行了选矿试验。试验以石灰为矿浆p H值调整剂,Cytec Aero 3894+Cytec Aero 5100(质量配合比为2∶1)为组合捕收剂,Cytec F507为起泡剂,在磨矿细度为-0.053 mm占85%情况下,采用1次粗选2次快速精选,快速精选尾矿、扫选精矿、扫选尾矿中的+0.053 mm粒级合并再磨至-0.01 mm占80%后,进行2次扫精选流程处理矿石,快速精选精矿与扫精选精矿合并的精矿铜品位为48.57%、回收率为88.34%。
Aiming at characteristics of complex dissemination and uneven particles size dissemination of copper minerals from Kamoa, Democratic Republic of Congo, beneficiation experiment was conducted by stage grinding stage separation process. With lime as a pH regulator, Cytec Aero 3894 ＋ Cytec Aero 5100 （ mass ratio of 2 ： 1 ） as combined collector, and Cy- tec F507 as foamer, at grinding fineness of 85% passing 0. 053 mm, through one roughing and two flash-cleaning, scavenging rough concentrate, flash-cleaning tailings and the ＋0. 053 mm coarse fraction of scavenging tailings combined and then regrind- ing to fineness of 80% passing 0. 01 mm, through two scavenger-cleaning process, then a combined concentrate of flash-clean- ing and scavenger-cleaning with 48. 57% Cu and recovery of 88.34% was obtained.
