| 摘 要： | 我国是天然石墨资源大国,储量、产量及出口量均居世界首位,但随着生产的发展,剩下的石墨矿品位较低,可选性下降,选矿回收率较低。通过实验,采用浮选法回收低品位石墨,使低碳石墨矿达到国家高碳标准,充分利用石墨资源,扩大石墨应用范围。试验以黑龙江鹤岗地区细鳞片石墨(固定碳含量为12.74%)为原料,采用浮选工艺,对该矿石采用一次粗选一次扫选,粗精矿五次再磨六次精选,中矿(1～3)合并再选,中矿4、5、6、7集中返回再磨Ⅰ的工艺流程,以煤油作捕收剂,2#油作起泡剂,生石灰作调整剂,使最终精矿品位提高到93.60%,回收率达91.42%。

| Abstract: | China is a big country of natural graphite resources.The reserves,production and export volume of graphite is first in the world,but with the development of production,the grade of the rest graphite is very low,and the optional drop result in the recovery rates decline.Through the experiment,we need to recovery the low grade graphite by flotation,make sure the grade of concentrate up to the national high-carbon standards,make full use of graphite resources to expand the scope of application of graphite.Base... |
