细鳞片难选石墨水力旋流器分级浮选试验研究
|
摘要
通过岩矿分析、物相分析以及化学全元素分析等方法对阜新某细鳞片石墨进行原矿特性分析,针对鳞片石墨形状不规则、片径细小且与脉石矿物侵染分布等特点,采用一种小锥角水力旋流器串联与多段磨浮相结合的工艺技术对细鳞片石墨矿进行提纯。在确定旋流器组及浮选条件的基础上进行开路试验、闭路试验,使最终石墨固定碳含量由6.58%提升至94.18%。
It explores the ore's characters of fine flake graphite in Fuxin under the methods of rock ore analysis, X-ray diffraction phase and chemical analysis. Apurification technology combine with small cone angle hydrocycloneseries and multistage grinding floating used to deal with the issues which the flake graphite shape is irregular, small piece diameter and the gangue minerals disseminated distribution. On the basis of the best condition of hydrocyclone and flotation, an open-circuit test and a close-circuit test was conducted. The eventually fixed carbon content of the graphite increased from 6.58% to 94.18%.
