Copper Processing TreatmentMar 01, 2013 · Additional benefits include nearzero emissions and the eventual decommissioning of the current slag mill and reverberatory furnace, which further improves the long term sustainability of the smelter." Resininpulp. The overall copper recovery can be increased significantly by using resininpulp (RIP) technology.
Recovery of cobalt, nickel, and copper from slags, using ...In the case of copper reverberatory furnace slag, mineralogical studies showed that the cobalt is present as CoO. Copper in the slag is mainly attributed to the presence of copperrich sulphides. The cobalt oxide, and, to a lesser extent, the copper oxide associated with the silie / oxide phases, is reduced by Fe from the alloy to form ...

Optimizing the Crystalline State of Cu Slag by Na2CO3 to ...Cu is the most important component in Cu slag, which is usually recovered by flotation. However, the crystalline state of Cu slag is not conducive to flotation, which limits the recovery of Cu. This study investigated the effect of Na2CO3 on the crystalline state of Cu slag and the recovery of Cu by flotation. The mechanism was investigated by thermodynamic, viscosity, Xray diffraction (XRD ...
