    Jul 16, 2017· To recover copper from the formed solution, liquid extraction with the solution of 0.34 mol/L DX-510A in kerosene is applied. Copper ions are recovered from the organic phase by reextraction with the 2.0 mol/L sulfuric acid solution. Cathodic copper is isolated from the sulfuric acid electrolyte at the current density of 1.5–2.0 A/dm 2.Flowsheet considerations for copper cobalt projects,The flowsheet route for copper is fairly well established while the processing options for cobalt vary considerably depending on the final product (metal or salt) the operator wishes to make. The mineralogy of ores in the area is typically associated with high gangue acid consumption during the leaching process.

    The acidic oxidative leach is a two stage process, where economic metals are first leached in oxygenated acidic solution, with the acidic leach slurry then neutralised to precipitate iron and other deleterious elements such as arsenic, prior to separation of the leached solids and recovery of the economic metals from the neutralised leach solution.Hydrometallurgical Processing an overview,Copper is obtained from a solution containing 25–30 g/l of copper by the SX/EW process. In many aspects, i.e., the mineralogical composition of the charge, the high efficiency of extraction of copper with the minimum ‘attack’ on pyrite and in the pressure leaching conditions, the process is similar to the process developed by the Sherritt
