Study on Removing Dissolvable Mn²⁺ from Manganese Residue by Oxidation at High Temperature

Abstract:

The removal of dissolvable Mn²⁺ from manganese residue was attempted using strong reduction at high temperature. The effects of the several parameters which including roasting temperature in range of 750-1050 °C and roasting time range of 60-360 min were investigated. An increase in roasting temperature from 750 °C to 1000 °C for 90 min increased manganese removal rate from 50.79% to 90.48%. But effect of roasting time on the rate of manganese removal was not obviously, just from 90.06% for 60 min to 94.76% for 360 min at 1000 °C.
