吉林某铜钼矿磨矿工艺探讨

Discussion for Grinding Technique of a Copper-molybdenum Mine in Jilin Province

吉林某铜钼矿具有回收价值的为辉钼矿和黄铜矿,浸染粒度以粗、细粒为主,不均匀嵌布。辉钼矿和黄铜矿除与脉石矿物嵌布关系紧密外,与其他金属矿物很少有嵌布关系,矿石结构构造较为简单。磨矿分级产品质量直接影响选别指标,合理确定磨矿细度,对简化磨矿流程、节省投资、降低能耗,提高选厂经济效益有着重要意义。

The ore which is based on recovery value is the molybdenite and the chalcopynte tlaat is trom a copper--molybdenum mine in Jilin. The disseminated grain size of the ore is mainly to be coarse and fine, the grain is inbuilt unevenly. The disseminated relationship of molybdenite and chalcopyrite to the metallic is not close besides the gangue, the texture and structure of the ore is simpler. The production quality of the ore which is from the grinding and classification flowsheet will influence the index directly, so it is im- portant to define the mog reasonably for simplifying grinding flowsheet, reducing investment outlay and energy consumption, and enhancing economic performance of the concentration plant.
