Abstract

Abstract

The graphiteore from Shaanxi province was used as the object in this research. On the basis of X-ray diffraction analysis and chemical analysis of the sample, a systematic experimental study on beneficiation process was implemented. And the optimum fineness of rough grinding, the amount of collector, frother and regulator and the density were determined. Then the whole flowsheets open-circuit test and closed-circuit test were carried out on this basis. The composition and morphology analysis were carried out on the closed-circuit flotation concentrate. The results showed that the ore was crystalline flake graphite with a fixed carbon content of 13.70%. The main gangue minerals are calciteandquartz. After systematic beneficiation test, the closed-circuit flowsheet of one roughing, one roughing, five regrinding and six cleaning was finally adopted. A good index of 95.92% fixed carbon content and 90.35% recovery of concentrate was obtained. The results of concentrate analysis showed that gangue minerals mainly existed in coarse class and fine class of concentrate. The size of flake graphite was mostly above 50 μm. The flake graphite crystallized well and its surface was smooth. The large flake graphite was abraded and a small amount of fine bright impurity mineral particles were attached to the surface.
