The combination of LIX 63 and Versatic 10 acts synergistically for the selective extraction of nickel and cobalt from impurities of manganese, magnesium, and calcium. Nickel extraction kinetics is, however, slow relative to cobalt. The present work exploited this difference to selectively remove cobalt from nickel, manganese, magnesium, and calcium mixtures using a synergistic solvent extraction approach. Experimental investigations were conducted to optimize the extraction parameters, which included phase ratios, concentration of extractants, and temperature variations. The results demonstrated a significant increase in the separation efficiency of cobalt over that of nickel, as well as the mitigation of the co-extraction of the aforementioned impurities. The findings contribute to the field of metal recovery by providing a more efficient method for the selective separation of valuable cobalt from complex mixtures, which has implications for improving processes in hydrometallurgical operations.
