摘　　要：西北某钢铁厂难选氧化铁矿进行了不同冷却条件下的焙烧矿弱磁-反浮选实验室试验。结果表明:焙烧矿冷却时继续保持还原气氛能提高金属铁的回收率,部分氧化后的磁选精矿反浮选,阳离子捕收剂用量较低。Roasted ore cooling mode magnetic separation cation reverse flotation.The laboratory test of weak magnetic reverse flotation of roasted iron ore under different cooling conditions was carried out in a refractory iron and steel plant in northwest China.The results show that the recovery of metal iron can be improved by keeping reducing atmosphere when the roasted ore is cooled,and the amount of cation collector is low after partial oxidation.

关 键 词：焙烧矿 冷却方式 磁选 阳离子反浮选
