Abstract—This study was carried out to develop a flotation procedure for an oxide copper ore from a Region in Central Africa for producing an 18% copper concentrate for downstream processing at maximum recovery from a 4% copper feed grade. The copper recoveries achieved from the test work were less than 50% despite changes in reagent ...

201861 · The formation of oxide layers on copper surface was studied by the means of transmission electron microscopy (TEM). A small aliquot of nanowire dispersion was sonicated in ultrasonic bath for 15 minutes, then drop casted on Ni grids and placed into the TEM column (Jeol FS 2200) after drying. Copper nanowires were analyzed within the …

2018924 · 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 sodium sulfide …
