Electrowinning of cobalt from a sulphate bath containing H3BO3 and NaF

Electrowinning of cobalt from a sulphate bath containing Na2SO4, NaF and H3BO3 individually and H3BO3 in combination with NaF and Na2SO4 was studied. From the preliminary study it was observed that a sulphate bath containing both NaF and H3BO3 gave the best results. The effects of various parameters, namely NaF, H3BO3 and cobalt concentrations, current density, bath temperature, bath pH, etc. on cathode current efficiency and on the nature of the deposit were studied. The results indicate that both H3BO3 and NaF in the sulphate bath contribute towards higher current efficiency and better deposit in the elecrowinning of cobalt.
