Comet Resources Ltd. provided the successful results of the final phase of specialist test work on natural flake graphite from its Springdale Graphite Project (Springdale) located in Western Australia. The results of optimisation work aimed at improving the yield in the production of spherical graphite (SPG) were highly successful. By classifying the material in an air classifier into fine and coarse fractions to separate the fines fraction prior to the production of the SPG, yield was improved from 30-40% in prior testing, to 60%, which is considered a good yield. Further, as less material was input into the process of spheronisation after the classifying stage was completed, the throughput increased and energy consumption was reduced. In addition to the positive results from optimisation on yield, testing for tap density on the 15 micron SPG produced revealed that tap density had also increased. Prior testing results for tap density of the 15 micron SPG were 0.90kg/l, however on the material that was produced after use of the air classifier, tap density increased to 0.93kg/l, which is in line with generally accepted commercial specification for production of SPG to be used in the manufacture of battery anode material for use in lithium-ion batteries. Test work completed initially in 2019 and 2020 identified that graphite concentrate from Springdale, in particular in the high grade mineralisation, was quite a unique product due to its very fine size fraction, and also due the platy nature of the fine flake. Recognising that these properties may potentially have applications for battery anode material, a decision was made earlier in 2021 to generate a bulk sample of graphite concentrate to send to Germany for evaluation by a specialist graphite test facility.
