水廠鐵礦鐵精礦品位整體動態優化

Overall dynamic optimization of iron concentrate grade in Shuichang Mine

  • 摘要: 以提高從礦山至高爐煉鐵廠的綜合效益為目標,開發了用于優化鐵精礦品位的專用軟件,用模糊綜合評判法確定優化的鐵精礦品位.當鐵精礦品位、成本和生鐵價格改變時,可用該軟件評估采礦、選礦、燒結、球團、煉鐵的總效益和生鐵產量.在建立選礦、燒結、球團、煉鐵數學模型的基礎上,用該軟件進行了水廠鐵礦精礦品位的優化,得出水廠鐵礦優化的精礦品位是TFe67.92%.

     

    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%.
