Abstract
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.
