Abstract:This study highlights a hydrometallurgical method for the purification, extraction, and beneficiation of a multi-elemental leach liquor obtained via reductive leaching of spessartine ore, for the production of high-grade manganese compound. During these treatments, the effect of Cyanex®272 concentrations, pH, aqueous: organic (A/O) was quantified. At optimal conditions (Temperature = 27 ± 2°C, 0.2 mol/L Cyanex®272, pH = 4.5, A/O = 1:1), manganese extraction efficiency was >90%. The stripping of the loaded orga… Show more
