Abstract The basic sintering characteristics of 4 kinds of iron ore concentrate used at AISC were investigated. On the basis of the results, the statistic model of proportioning ore for sinter was established by optimal design of experiment. Using this model, the proportion of each kind of ore was obtained for obtaining optimum and worst sintering indexes. The optimum proportioning ore was proposed. The industrial trial results of optimum ore proportioning show that sinter techeconomic indexes, especially including sinter ore size distribution and solid fuel consumption are improved. It was found that adding iron ore concentrate A for pelletizing has superiority, the bentonite proportion is reduced by 8.69% and drum strength is increased by 0.35%.
