承德某钒钛磁铁矿尾矿资源化利用技术研究
Multipurpose Utilization of Mineral Resources(2020)
Abstract
承德某钒钛磁铁矿选铁尾矿中TiO2品位2.60%,TFe品位7.73%.针对该尾矿中钛铁矿资源尚未回收利用的问题现状,根据尾矿性质,本研究采用“磁重联合阶磨阶选”预富集工艺;以及采用硫酸、EM-B作为调整剂,EM-3作为捕收剂,经过一次粗选、一次扫选、五次精选的钛浮选流程,最终获得了TiO2品位46.23%、浮选作业回收率83.25%、相对选铁尾矿回收率42.03%的钛铁矿精矿产品,实现了该尾矿资源化综合回收利用,为此类矿山提供合理可行的资源利用技术方案.
