Abstract: Graphite sample from Mayo-Butale and Walol-Kolel were beneficiated by froth floatation and a yield of 52.1% and 62.65% were obtained for the two samples respectively on a second float. On aching the carbon content was improved from 36.6% and 33.6% for the raw samples to 85.0% and 83.4% for the beneficiated samples. Chemical analysis of the ash using X-ray fluorescence (XRF) showed that SiO2, Fe2O3, and Al2O3 were present in high quantity. Others present in low quantity were K2O, CaO and TiO2. On determining the powdered density of 2280Kg/m3 and 236oKg/m3 were obtained for the two samples which compares favorably to 2260Kg/m3 for pure graphite. Micro structural studies revealed that the two graphite samples had a flake size of 0.5mm.
