Improving Flocculation Performance of Copper Flotation …
Large amounts of tailings are produced when copper minerals are concentrated by flotation. For instance, the flotation process is performed with water containing 25–35% wt solid ratio and is consumed 1.9–3 m 3 water per ton of ore processed (Gunson et al., 2012; Li et al., 2019).
Development of copper recovery process from flotation …
The total copper recovered from its ore through flotation process is about 56% [6, 18], which indicates that the flotation tailings still contain valuable copper components such as chalcopyrite. In addition, old flotation tailings sometimes have a higher copper grade (0.2–0.4%) than that of low‒grade ores (0.2‒0.3%).
A New Technique for Recovering Copper From Complex Copper Oxide Ore …
Copper oxide ore has a complex composition, and a low recovery rate is often achieved via the traditional sorting method. A new combined process of flotation–high-gradient magnetic separation–leaching is proposed here to recover copper minerals. The test results showed that the flotation process was successful when using …
