Abstract: In order to reach the aim of increasing the integrated benefit from mines to blast furnace works, an exclusive software for optimizing iron concentrate grade was developed. The optimum iron concentrate grade was established by the method of fuzzy integrated evaluation. When iron concentrate grade, cost and pig iron price change the software can be used for evaluation of the total benefit of mining, mineral processing, sintering, palletizing and ironmaking, and the output of pig iron. Based on the mathematical models of mineral processing, sintering, palletizing and ironmaking, the software was used for optimization of the iron concentrate grade in Shuichang Mine, China. The optimum iron concentrate grade in Shuichang Mine is TFe 67.92%.
