前言目前,在国内国际市场上具有竞争能力的天然鳞片石墨是+100目以上的大鳞片产品。因此,在石墨生产中改进工艺,采取保护鳞片措施,提高大鳞片产率,是当前石墨选矿工艺中的一个重要问题。某矿是我国目前开采的最大的品质石墨矿之一。矿石质地优良,开采条件好。该矿目前采用阶段密矿阶段选别流程,对鳞片保护有一定的作用,但尚未采取更有效的措施保护大鳞片,精矿中+100目含量一般25％
Foreword At present, the natural flake graphite which is competitive in the domestic and international markets is a scale flake product of +100 mesh or more. Therefore, it is an important issue in the current graphite beneficiation process to improve the technology in the production of graphite, to take measures to protect scales and improve the yield of large scale flakes. A mine is one of the largest quality graphite mines currently mined in China. Ore texture is good, mining conditions are good. The mine is currently using the phase of dense stage sorting process, the protection of scales have a certain role, but not yet take more effective measures to protect the large scales, +100 mesh concentrate content is generally 25%
