彝良难选鲕状赤褐铁矿提铁降磷工艺研究OACSTPCD
Experimental Study on Iron Improvement and Phosphorus Reduction for a Refractory Oolitic Hematite Limonite Ore in Yiliang
针对彝良难选鲕状赤褐铁矿进行了系统的选矿试验研究,采用强磁选—反浮选及选择性絮凝浮选脱泥—反浮选均可以得到较好的选别指标:在强磁选—反浮选小型闭路试验中可以得到铁品位54.70％、回收率达79.44％、含磷仅0.17％的铁精矿；在选择性絮凝后浮选脱泥—反浮选的工艺流程中可以得到铁品位54.63％、铁回收率达77.62％、含磷仅0.15％的铁精矿.
The systematic experimental research was carried out on a refractory oolitic hematite limonite ore in Yiliang, good index were obtained both by flowsheet of " high - intensity magnetic concentration - reverse floatation" and " floatation desliming after selective flocculation - reverse floatation". An iron concentrate containing 54. 70% TFe bearing 0. 17% P with a recovery of 79. 44% was obtained by the former flowsheet, and an iron concentrate containing 54…查看全部>>
