It requires higher temperatures (>1150° to 1250°C) to produce strong enough manganese ore pellets, which makes it a more expensive process. On heating of green pellets, manganese dioxide (MnO 2) and manganic oxide (Mn 2 O 3) dissociate in endothermic reactions that impose additional fuel consumption. Fine grinding of the material would also be necessary for pelletizing. Consequently, pelletizing appears to be a rather expensive solution for manganese ore, particularly compared with iron ...
