Medium high carbon natural flake graphite

A two steps in the production of carbon and high carbon flake graphite method, its characteristic is that, including the first step to select grinding mill and the second step is to select, among them: the first step: S11 flake graphite ore after crushing, grinding and flotation reagents and roughing, after mixing scavenging, get rough concentrate and tailings, the tailings discarded; Speed 12 rough concentrate after hydrocyclone and spiral classifier classification, with a wet ball mill grinding again, and to select, / S13 selected the bubble product into thickener or thick concentrated into the ball mill or stirring mill grinding, select again, subsequent selection of foam products are thick, 2 ~ 4 times of mixing and grinding, and 3 ~ 5 times, fixed carbon content 85% ~ 90% of the carbon in the flake graphite ore concentrate. The selection of the medium mineral products of the selected work is returned to S11 and S12. Step 2: carbon filtration dehydration after natural flake graphite concentrate in place more than 15 days, after joining agents mixing into the mixing and grinding and selection, on the basis of fixed carbon content of high and low, after 2 ~ 4 times, 3 ~ 5 times featured two steps of the selection process, fixed carbon content 95% ~ 97% of the high and low carbon flake graphite concentrate fixed carbon content of carbon in graphite.
