摘要
我国有大量的铁矿石资源无法通过常规选矿方法进行开发利用,流态化磁化焙烧是处理该类矿石最有效的方法,成为近年来的研究热点。综述了铁矿石磁化焙烧机理研究进展,总结了流态化磁化焙烧技术与装备发展历史和研发现状,重点介绍了沸腾炉磁化焙烧、闪速磁化焙烧、流化床磁化焙烧及悬浮磁化焙烧技术装备特点和应用示范,并分析了流态化磁化焙烧技术在菱铁矿、褐铁矿、赤铁矿等难选弱磁性铁矿资源及铁尾矿二次资源利用方面的发展前景。
There is a large amount of refractory iron ore resources that cannot be exploited by conventional ore dressing methods in China. Fluidized magnetization roasting is the most effective method for treating this iron ore,and has become a re?search hotspot in recent years. In the present review,the magnetization roasting mechanismof iron ore is introduced,and the development history and technical status of fluidized magnetization roasting are summarized,with the emphasis on introduc?ing the technical equipment features and application demonstration of various fluidized magnetization roastingtechnologies,in?cluding boiling furnace,flash magnetization roaster,fluidized bed,and suspended magnetization roaster. The application prospect of thefluidized magnetization roasting technology is also analyzed for low-grade refractory siderite,limonite,hema?tite,and iron-containing tailings.
