Abstract:The binding phase strength of mixed iron ore with high limonite ratio was determined by micro-sintering apparatus at different sintering temperature, basicity and MgO content. The results reveal that, binding phase strength of mixed iron ore increased at first and then decreased as sintering temperature, basicity and MgO content increased. It reached the highest value when the sintering temperature was 1 280 ℃, alkalinity was 1.6 and mass percent of MgO was 2.0%. Limonite ratio should be reduced appropriately in production, so that the mixed iron ore has adequate binding phase strength.
