摘要： 高品质大鳞片石墨具有较高的使用价值和经济价值，为防止石墨大鳞片的破碎，对坦桑尼亚某鳞片石墨矿石采用阶段磨矿浮选—预先分目的工艺流程进行了试验研究。试验通过筛分获得了+0.15 mm大鳞片石墨精矿，-0.15 mm石墨经过阶段再磨精选，得到了高碳细粒级石墨精矿，闭路试验获得的大鳞片石墨固定碳品位为96.04%、回收率为55.84%，细粒级石墨固定碳品位为95.43%、回收率为38.73%，精矿总回收率为94.57%。该工艺流程有效保护了石墨鳞片的完整性，提高了大鳞片产率。

Abstract: High-quality large flake graphite has high application value and economic value. In order to prevent the fragmentation of large flake graphite，the stage grinding flotation-pre-separation process of a large flake graphite ore in Tanzania was studied. The +0.15 mm large flake graphite concentrate was ob⁃ tained by screening，and the high carbon fine-grained graphite concentrate was obtained by stage grinding and cleaning of -0.15 mm graphite. The fixed carbon grade of large flake graphite was 96.04% and the re⁃ covery rate was 55.84%. The fixed carbon grade of fine-grained graphite was 95.43% and the recovery rate was 38.73%. The total recovery rate of concentrate was 94.57%. The process effectively protects the integri⁃ ty of graphite flakes and improves the yield of large flakes.

Key words: flake graphite, stage-grinding and concentration, mesh separation beforehand
