Abstract:A low quality ore called Mount Gibson was researched for using during sintering. Firstly, high temperature properties of ore were studied by micro sintering equipment, based on which, sinter pot tesr was carried out to verify the application of Mount Gibson. Results show that, the assimilation and liquid phase fluidity of Mount Gibson both are high, which can be used as a measure to make up the disadvantage of that ore with high SiO2 and Al2O3 content and bad size composition. At last, in industrial practice, usage of Mount Gibson with ratio of 6% was feasible in sintering and blast furnace.
