| 摘 要： | 云南某铁选矿厂的尾矿含铁28.68%、二氧化硅40.95%,开展了摇床重选、高梯度强磁选、正浮选、阴离子反浮选和阳离子反浮选等五种工艺的探索对比,阳离子反浮选是较佳的提铁降硅工艺流程。该铁尾矿经阳离子反浮选工艺选别后,获得精矿含铁51.13%、二氧化硅11.54%、回收率64.76%的技术经济指标,为该矿山企业综合回收利用二次资源提供了决策的依据。

| Abstract: | A kind of iron concentrator tailings in Yunnan province with iron content of 28.68% and silica content of 0.95% is processed by five different anti-flotation processes such as :shaking table gravity separation,high-gradient strong magnetic separation,flotation,anionic reverse flotation,as well as cationic reverse flotation.The results are compared and show that cationic reverse flotation is a better processing method for recovery iron and reduce silicon.By cationic reverse flotation process,concentrate with... |
