Basics of Cobalt Electrowinning in Under 3 Minutes
Cobalt has an electrochemical potential of E0 = -0.28 V, while Nickel’s is E0 = -0.25 V. If in solution together, it’s almost impossible to selectively electrowin either of these metals. 2) Impurities in Solution (Fe, Cr, Cu, Pb, Zn etc.)

ELECTROWINNING OF COBALT FROM A 1980) and
and plating duration on cobalt electrowinning from a complex sulfate-chloride system were studied. Experimental results showed that cobalt concentration had a significant influence on cobalt deposition from the specific system. Current efficiency decreased markedly when cobalt concentration was reduced to less than 10g/L.

COMPARISON OF SOLVENT EXTRACTION AND SELECTIVE
precipitation steps to purify the solution before electrowinning. The cobalt stream is then subjected to final precipitation and re-leaching with sulphuric acid in aim to obtain a suitable cobalt concentration in the advance electrolyte. Many cobalt plants still follow this classic technique of selective precipitation as the purification method.

US4288305A Process for electrowinning nickel or cobalt
A process for electrowinning nickel or cobalt from an electrolyte in apparatus having spaced insoluble anodes and cathodes. Each anode is provided with diaphram means for defining an anolyte compartment. A frothing agent is introduced into the feed electrolyte which expedites the withdrawal of spent electrolyte and anodically generated gases.
