| Abstract: | Flotation technology was be used to process the fine flake graphite ore (fixed carbon content of 13.27%)in Heilongjiang luobei area. Based on the study of ore process mineralogy and floatation conditional tests, stage-grinding and stage concentration was selected with split flow technology by screening. We got the large flake graphite concentrate ( 0.15mm) and fine flake graphite (-0.15mm). Fine flake graphite concentrate (-0.15mm) was enriched by stage-grinding and stage concentration. The results showed that, an graphite concentrate with a fixed carbon content of 96.11% and a recovery of 91.30% can be obtained by the closed-circuit bench test, and the 0.15mm flake graphite yield in concentrate is 16.08%. |
