Summary:Via the thermodynamic analysis of high silicon manganese soot precipitation process. Potential-oxidation state-ΔG diagram, E-pH diagram, micro-region morphology of manganese soot and X-ray energy spectrum analysis, we can know: under high temperature leaching conditions, the leaching system needs to maintain a relatively high initial acid concentration in order to achieve leaching of Mn2+ and increase the pressure leaching rate.
