【摘要】 云南西定铁矿中铁品位为41.55%,主要含有磁铁矿和赤褐铁矿。本研究采用摇床重选、弱磁选和强磁选的选矿方法验证该铁矿的可选性。采用"两段磨矿、一粗一精"的弱磁选流程可以选出品位为60.31%的磁铁矿精矿。尾矿中的赤褐铁矿不易回收,综合选别成本考虑,目前西定铁矿为难利用矿石。更多还原

【Abstract】 The iron grade of Xiding iron mine in Yunnan province is 41.55%,which mainly contains magnetite and hematite limonite.In this study,shaking table gravity separation,low intensity magnetic separation and high intensity magnetic separation were used to verify the separability of the iron ore.The magnetite concentrate with a grade of 60.31% can be selected by the low intensity magnetic separation process of "two stages grinding,one roughing and one cleaning".The hematite and limonite in tailings is not easy to recover.Considering the comprehensive separation cost,it is difficult to use the ore in Xiding iron mine at present.更多还原
