摘要
介绍了铁坑褐铁矿的两种分选工艺：强磁－正浮－强磁和强磁－反浮选，分别获得精矿品位５２．０９％、５４．４８％，回收率７５．２９％、７０．７８％的试验指标，比同期生产指标品位分别高１．０７、３．４６个百分点，回收率高１０．１３、５．６２个百分点。
Abstract The paper presents two beneficiation technologies for Tieken limonite ore: high-intensity-magnetic separation-direct-floation-high-separation and high-intensity-magnetic-separation-reverse-flotation,which gained the experimental results of grade of 52. 09% and 54. 48%,and of recovery of 75. 29% and 70. 78% respectively. When compared to the production indexes of the same period,the grade was 1. 07% and 3. 46% higher and the recovery, 10. 13% and 5. 62% higher respectively.
