摘要
针对庙沟铁矿露天矿开采接近尾声、采场空间狭小、矿岩剥离工作受到限制、岩石混入量增加等问题,以"多碎少磨"的选矿理念,在矿石破碎阶段将混入的废石提前甩出,减少选磨矿环节压力,提高入磨原矿品位。
To address the problems arising at late-stage mining of Miaogou iron ores such as cramped mining space, restricted rock and ore stripping work, increased rate of rock drop-in and based on beneficiation concept of more crushing and less grinding, drop-in spoils are tossed out in advance at ore grinding stage so that ore grinding and separation process will be less stressed, energy will be saved, grinding ore grade will be improved.
