鲕状赤铁矿因其微细粒嵌布、结构复杂等特点,一直被认为是世界选矿难题.本文主要研究了其在我国的利用现状,以及强磁选-反浮选、絮凝-强磁选、磁化焙烧-磁选等传统基础选别技术,并讨论了一种高效选别技术——深度还原,对鲕状赤铁矿的选别具有很重要的现实意义.%Because of oolitic hematite micro-fine disseminated and complex structure and other characteristics, has been considered the world's mineral processing problems. This paper studies the use of its current situation in China and some traditional sorting techniques such as strong magnetic separation-reverse flotation, flocculation-intensity magnetic separation, magnetic roasting-magnetic, and discuss an efficient sorting technique-the deep reduction, which has important practical significance for oolitic hematite sorting.
