| 摘 要： | 黑龙江某细鳞片石墨矿采用浮选工艺进行选别,采用改进后的KYZB型浮选柱,对生产现场中不同浮选作业的矿浆,进行了充气量、给矿速度等不同浮选条件下的鳞片石墨柱浮选新工艺研究。研究结果表明,相比于浮选机,KYZB型浮选柱精矿回收率偏低,但是可以获得固定碳含量更高的浮选精矿。通过浮选柱产品的粒度筛析,查找了回收率偏低的原因和鳞片石墨柱浮选的重要影响因素。

| Abstract: | Flotation technology was be used to process a fine flake graphite ore in Heilongjiang. Research is made on the different flotation pulp by improved KYZB flotation column with some factors such as aeration rate and feeding capacity etc. Test results show that the improved KYZB flotation column has superiority in concentrate grade compare to the flotation machine, with the lower recovery. The main factors that affect the recovery and column flotation are found by sieve analysis of the concentrate and tailings. |

| Keywords: | flake graphite flotation column floatation technology particle size |
