摘要
针对某菱铁矿(FeCO3)进行磁化焙烧处理,使FeCO3分解为氧化铁,再经碳还原为Fe3O4,焙砂再经过弱磁选选矿,使矿石中的铁得到了有效回收。
For magnetic roasting of a siderite, FeCO3 is decomposed into iron oxide which is reduced into Fe3O4 by carbon, low intensity magnetic separation is carried out after roasting so that . iron from the ore is efficiently recovered.
