| Abstract: | It is regional metamorphic deposit for Lushan graphite in Henan Province.We carried on the roughing condition testing,stage-grinding and stage concentration process testing,stage-grinding and stage concentration process testing and mesh separation beforehand testing according to the ore characters.The research result shows that stage grinding is the available method for protecting crystalline flake graphite,and to improve the big flakes rate of graphite with the method of mesh separation beforehand.We get the concentrate grade of C 固 at 90.62% while the crude ore at the grade of 3.65%,and the content of TS is 0.072%,with the recovery of 88.11%,the production rate of big flake graphite(+0.147mm)among which is 0.46% with the grade of C 固 at 91.58%,and the big flakes rate in concentrate is 12.96%. |
