iron ore sinter pellets reducibility ghana

AbstractThe effect of lime and silica addition on the reducibility of sintered iron ore and synthetic hematite pellets was investigated The addition of lime andor silica up to about 10 total to sintered synthetic hematite pellets has little effect on the reducibility at 900°C Lime additions with or without silica lower the reducibility of sintered hematite and magnetite ore pellets
