摘要
对平均嵌布粒度仅15μm的哈萨克斯坦巴尔布拉乌赤铁矿进行选矿工艺研究,最终开发出强磁-反浮选微细粒嵌布赤铁矿选矿工艺。采用强磁预先抛尾,而后再磨,应用高效调整剂CN及捕收剂BK959,经一次粗选、两次扫选、三次精选的反浮选处理,有效实现难选赤铁矿的浮选分离,得到了高品位的赤铁矿精矿,铁精矿品位达到66％以上、回收率达到70％以上。为该矿的工业开发提供了选矿技术支撑。
In this paper, with the flotation research on hematite in Kazakhstan, which average particle size is only 15 μm the flotation technology of high magnetic-reverse flotation for micronization embed hematite is finally developed. After high magnetic throwing firstly, dealed with regrinding and high effective regulator CN and collector BK959, and reverse flotation of one rougher two scavengers three cleaners, the hematite flotation is successfully realized. The degree of hematite concentration is high, up to 66%, recovery is up to 70%.
