Chemical Kinetic and Mechanistic Investigation of Cobalt and Manganese Recovery from Aqueous Solutions by Ozone Oxidative Precipitation

, MnOOH) formed nucleation sites that promoted Co adsorption and coprecipitation, a mechanism supported by SEM-EDS, XRD, FT-IR, XPS, and Zeta Potential analyses confirming the formation of Mn oxide phases facilitating surface-mediated Co capture. Overall, these findings provide mechanistic and kinetic insight into ozone-based Co-Mn recovery and establish a basis for process design and optimization in critical metal recovery applications.
