Study on process mineralogical characteristics of flake graphite ore
The larger the flake diameter of flake graphite,the higher the value,so the flake should be strictly protected during the processing of flake graphite ore.In this paper,the mineralogy of large graphite deposits in Jixi area was studied.The mineral composition,morphology,distribution and particle size of graphite flakes were detected by MLA method,and the effects of mineralogy on graphite dissociation,flake breakage and flotation operation were analyzed.The results showed that the grade of Jixi graphite ore is 5.05%.The par-ticle size above 0.15mm reached 51.68%,and the fine particle graphite was mostly covered by gangue miner-als.The grinding method of agitation grinding was more effective for the dissociation of fine particle graphite and the efficient protection of large scale graphite.
