摘要：The crystallisation behaviour of Fe2O3 during preheating and roasting of pellets made from mixed magnetite–haematite (M–H) concentrates has been studied. The results indicate that the strength of pellets is mainly provided by the crystalline connections between Fe2O3 particles during preheating. This occurs because the activity of Fe2O3 from secondary haematite (SH) (oxidised from magnetite concentrate, SH) is higher than from original haematite (OH). In the roasting process, when temperature is lower than 1250°C, the strength is mainly provided by the development, connection and growth of Fe2
