介绍了钢渣的矿物组成。从内部循环、工程回填、筑路材料、污水净化、脱硫、土壤肥料、微晶玻璃、陶瓷、水泥等方面对目前国内外钢渣的综合应用进行了简要评述。综合地对比了目前从钢渣中回收铁的主要方法:磁选、还原、氧化。从工艺效果和环境保护的长期发展来看,通过氧化将钢渣中非磁性氧化亚铁转化成磁性四氧化三铁的方法在未来将会受到越来越多的关注。
The mineral composition of steel slag is introduced. From the internal circulation, engineering backfill, road construction materials, sewage purification, desulfurization, soil fertilizers, glass ceramics, ceramics, cement and other aspects of the current domestic and foreign steel slag comprehensive application of a brief review. Comprehensive comparison of the current main method of recovering iron from steel slag: magnetic separation, reduction, oxidation. From the perspective of process effectiveness and long-term development of environmental protection, more and more attention will be paid in the future to the method of converting non-magnetic ferrous oxide in steel slag into magnetic ferriferous oxide by oxidation.
