摘　　要：论述了选别小孤山矿区废弃高碳酸铁矿石的新方法新工艺,选别后精矿品位达65%以上,并在大球三选车间对不同碳酸铁含量的矿石进行了阶段性工业试验,取得精矿品位66%以上、尾矿品位16%、金属回收率51%的选别指标,且选别指标稳定。The paper discusses the new method and new process for separation of waste high carbon acid iron ore in Xiaogushan Orefield. After separation, concentrate grade will reach more than 65%. It also conducts phased pilot test for iron ore with different iron carbonate content in No. 3 Separation Plant Building, obtaining a separation index of concentrate grade more than 66 %, tailings grade 16 %, and metal recovery rate 51%. The separation index is stable. It opens up a new approach for overall development of utilization of high iron carbonate magnetite ore.
