| 摘 要： | 针对国外某大鳞片石墨矿, 结合磨矿细度与浮选精矿筛析数据, 在保护矿石中大鳞片石墨的同时, 简化了工艺流程, 最终采取阶段磨矿、一粗两精一扫-筛分分级的浮选工艺流程, 获得了产率4.37%、品位92.81%、回收率79.59%的大鳞片石墨精矿, 以及产率0.80%、品位91.23%、回收率14.29%的细鳞片石墨精矿。

| Abstract: | Aiming at an overseas graphite ore, the process was simplified based on the analyses of the grinding fineness and the particle size of flotation concentrate by screening, while protecting the large-scale graphite sheets therein. A flowsheet, consisting of a staged grinding process, a flotation process with one stage of roughing, one stage of scavenging and two stages of cleaning, and a screening process, was adopted in the experiment, resulting in the obtained concentrate of large-scale graphite sheets with yield, grade and recovery of 4.37%, 92.81% and 79.59% respectively, and the obtained concentrate of fine sheets with yield, grade and recovery of 0.80%, 91.23% and 14.29%, respectively. |
