摘要
本文阐述了包头磁选铁精矿的反浮选脱氟工艺。根据磁选精矿的特性,深入研究了磨矿细度、浮选浓度和不同捕收剂对磁选精矿脱氟的影响。试验结果表明,在不太细的磨矿粒度条件下,采用该反浮工艺,能有效的降低磁选精矿的氟、磷等杂质,获得优质铁精矿,并通过选铁降氟扩大连续试验和工业分流试验得到验证。
This paper describes the technique for removing fluorine by reverse flotation. According to the characteristics of iron concentrate from magnetic separation operation, the influence of grind, pulp density and collectors on the results of fluorine removal is investigated The testing results show that at not too fine grind the content of impurities, such as F and P can be effectively reduced by using the reverse flotation technique, thus obtaining iron concentrate of high quality. The technique has been approved by extended continous tests and industrial split-flow tests.
