摘要
提高攀枝花钒钛磁铁矿品位和降低ＴｉＯ２ 含量的试验研究结果表明，通过对现攀枝花钒钛磁铁精矿进行脱磁—再磨—磁选，可以将钒钛磁铁矿精矿品位提高到５５ ％ ＴＦｅ 以上，而精矿中的ＴｉＯ２ 含量仅提高０－１６ 个百分点，使实际进入高炉的ＴｉＯ２ 总量降低７ ％ 。通过计算，在保证高炉渣中ＴｉＯ２ 含量＜ ２５ ％ 条件下，通过配矿可使烧结矿品位提高到４９ ％ ，对降低高炉渣量、提高高炉产量。
Experimentalresults ofimprovementof Panzhihua vanadictitanomagnetite concentrate grade and re duction of TiO2 grade indicate thatthe concentrate grade of vanadic titanomagnetite can be increased to over 55 % TFe ,while TiO2gradeisonlyincreased by 0 .16 % andtotalamountofTiO2into blastfurnaceis decreased by 7 % through demagnetization - regrinding - magnetic separation forthe existing Panzhihua vanadictitano magnetite concentrate.Underthe conditionsof TiO2content < 25 % in blastfurnaceslagsintergrade can bein creased to 49 % with ore matching by meansofcalculation ,which hassome outstanding effects onthe reduction ofslag volume ,theimprovement of blastfurnace productivity andthe reduction ofcoke rate .
