Study on removing dissolvable Mn2+ from manganese residue by oxidation at high temperature

摘要：

　　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 o℃ and roasting time range of 60-360 min were investigated.An increase in roasting temperature from 750 ℃ to 1000 ℃ 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 ℃.
