| 摘 要： | 对黑龙江某石墨矿进行了工艺矿物学研究,查明了矿石中石墨的赋存状态,并就影响选矿指标的矿物学因素进行了分析。工艺矿物学研究结果表明,该石墨矿属鳞片石墨矿,选别作业时容易获得较理想的选矿指标,但矿石中的石墨嵌布粒度细,选别过程中需要细磨,细磨会破坏部分已解离的石墨大鳞片,降低大鳞片石墨产率,因此在选矿过程需加强对大鳞片石墨的保护,尽可能早回收；脉石矿物中含有一定量的白云母以及少量的绿泥石、高岭石,对石墨精选有一定影响。

| Abstract: | This paper performs a research on process mineralogy of a graphite ore, by which the mode of occurrence of graphite in the ore is investigated, and an analysis on the mineralogy factors which influence the mineral processing targets is carried on. The results of process mineralogy show that, this graphite ore is flake graphite ore , and it is easy to achieve more ideal mineral processing targets. However, the grain size of graphite in the ore is fine, and the fine grinding fineness is needed in mineral processing. The fine grinding will destroy the graphite flake, reducing the large scale graphite production rate, so it is needed to protect large graphite flake, recycling as early as possible in the mineral processing. In addition, a amount of muscovite and a small quantity of chlorite and kaolinite in gangue minerals will effect graphite cleaning. |
