Kumar, Vinay and Pandey, B D and Agrawal, A and Bagchi, D and Kumari, S and Sahu, S K (2005) Value addition in the processing of copper bleed solution by solvent extraction process. In: Proceedings of the International solvent extraction conference, 2005.
Copper bleed solution generated during the electrorefining of anode copper has been used for the recovery of metals as value added products viz. metal powders following partial decopperisation, solvent extraction and electrowinning. In this process, a mixed crystal containing copper and nickel sulphates is produced from the partially decopperised bleed solution by crystallization. The mixed crystal is dissolved and iron is removed by precipitation. The copper is extracted from the purified solution using LIX84 diluted in kerosene leaving nickel in the aqueous raffinate. Bench scale simulation study for the separation of copper and nickel is further confirmed by extracting copper in a mixer settler unit. The purified solution has been used for producing copper and nickel powders by electrolysis.
