Study on Ore Characteristics and Beneficiability of Three Flaky Graphite Mines in Africa

Three flaky graphite mines in the regions of Madagascar Anbahita, Mozambique Ancuaba, and Tanzania Chilalo, were used to study the ore characteristics and grain size. The results show that the graphite mines of these three areas are high quality and large-flaky graphite resource with similar minerals components. Cumulative distribution rates of +0.18mm size fraction of graphite particles in Anbahita, Ancuaba and Chilalo are 92.62%, 98.33% and 98.87%, respectively. Cumulative distribution rates of +0.85 mm size fraction of graphite particles in Anbahita, Ancuaba and Chilalo are 13.13%, 52.70% and 61.79%, respectively. The graphite flake of Chilalo is the largest in these three areas. The +0.15 mm size fractions of graphite in these three regions are much higher than the same type of graphite ore in China. The beneficiability of these three samples are all relatively favourable. Among them, the flaky size of Ancuaba concentrate is the largest, the flaky size of Anbahita concentrate is the finest. These research results provide a significant reference for the beneficiation and down-stream processing of graphite resource in these areas.
