介绍CPT系列浮选柱的工作原理及在我矿的应用实践。分析了浮选柱的空气流速率、冲洗水偏流、界面高度等工作参数,指出了气体分散器SlamJet技术在解决充气器易结钙堵塞上的优越性。CPT系列浮选柱可提高浮选作业的自动控制程度,解决生产实践中存在的精选铜精矿的质量差、回收率低等问题,进而为CPT系列浮选柱的广泛应用奠定了基础。云南迪庆矿业开发有限责任公司羊拉铜矿-选厂成功将该系列浮选柱用于铜精选作业,大大提高了铜精矿的精选效率及铜精矿的精矿品位,铜精矿品位由15.34%提高到17.68%,回收率由77.66%提高到82.97%,取得了良好的技术经济效益。 相似文献

某低品位钼铜矿石选矿试验研究 总被引:1,自引:0,他引:1
某钼铜矿石是一种以钼为主、并伴生铜矿物的低品位钼铜矿石,原矿含钼仅0.045%、含铜0.025%,无其它有价值的金属元素,试验采用先优先混合浮选将钼铜金属矿物同时富集后,再进行钼铜分离的选矿工艺,取得了钼精矿钼品位53.25%~50.4%(含铜0.30%~1.514%,取决于精选作业次数)、混合浮选开路作业回收率70.09%、分离浮选开路作业回收率55.89%~82.42%、开路作业总回收率为39.17%~57.77%;铜精矿含铜品位22.23%(含钼2.36%)、混合浮选作业回收率46.82%、分离浮选回收率90.45%、开路总回收率为42.35%的较好指标。如果条件允许能够进行闭路浮选试验,可能会取得更好的技术经济指标。 相似文献

Pb–Zn–Cu complex ore from Bal?kesir–?vrindi district have been concentrated by GESOM A.?. using a selective mechanical flotation technique. Ore feeds containing 3.23% Pb, 0.52% Cu, and 2.71% Zn were concentrated by six stages of cleaning and four stages of scavenging. The final zinc concentrate which contains 2.13% Pb, 1.14% Cu, and 52.77% Zn were produced with 61.38% Zn recovery. In this study, the effects of air rate, bubble diameter, gas holdup, and superficial air rate on the column flotation performance were investigated. In order to obtain best results, operation parameters were optimized. Besides, the number of cleaning and scavenging stages of zinc circuit was reduced by using column flotation instead of mechanical flotation. Hence, higher grade zinc concentrates with higher recovery were obtained. Using three stages of cleaning and three stages of scavenging, the zinc concentrate having 58.81% Zn was produced with a recovery of 74.21% indicating an improvement in final zinc concentrate. This achievement of column flotation method was recommended as an alternative method for the zinc circuit to the plant mentioned above, since it will reduce the operating costs. 相似文献
