摘要
根据贾家堡子7号矿体的原矿性质,进行了阶段磨矿、弱磁选-磁筛流程,阶段磨矿、全磁选流程,阶段磨矿、弱磁选-阴离子反浮选流程试验。以阶段磨矿、弱磁选-磁筛流程效果最好,可以获得铁精矿品位67.19%、回收率为84.84%的指标。
In light of the properties of the run-of-mine ore from JiaJiabaozi 7# ore body, various processes were used for this ore, including the process of staged grinding-low intensity magnetic separation-magnetic field-screening, the process of staged grinding-low intensity magnetic separation of total ore and the process of staged grinding-low intensity magnetic separation-anionic reverse flotation. The best result was achieved by the process of staged grinding-low intensity magnetic separation-magnetic field-screening, which obtained an iron concentrate grading 67.19% at a recovery of 84.84%.
