Flotation of copper oxide minerals by mixed collectors

摘要

In this study, the effects of important factors on malachite exploited from Tibet are investigated. Dosages of activating agents, depressants and collectors are essential to the effective recovery of copper in the flotation. The mixed collector ratio of SIBX: Armac C was varied as 0:1, 1:1, 1:2, 1:3, and 1:4. This investigation showed that using Armac C in conjunction with traditional SIBX collectors can successfully simultaneously recover copper oxides by flotation. The rougher scavenger copper recovery was as high as 85.2%.
