Iron ores with high combined water content have goethite as the major component and porosity of the ores after calcinations are large. Hence, their assimilability with melt formed during sintering is considerably high. At the condition of limited concentration of CaO, this property leads to the dif・ulties associated with insuf・ient ・Vidity
