The imputities present in South Australian graphite concentrates and various chemical methods for the removal of these have been examined. It was found that the best of theses methods could be combined to give a process for the complete beneficiation of high grade concentrates. On examination, the economic aspects of the proposed process indicate that it is capable of being profitably operated on an industrial scale. The results of this work support the claim that the purity achieved by application of the proposed process is higher than that obtained by other methods of purification. The claims that chemical benificiation methods reduce graphite flake size and that appreciable amounts of reagents are adsorbed on graphite during processing have been disproved.
