Northern Graphite Corporation (TSXV:NGC,OTCQX:NGPHF) announced it has increased spherical graphite testing to Bissett Creek deposit up to 99.99% graphitic carbon.
As quoted in the press release:
Hazen Research’s initial mandate was to test the laboratory process developed by Northern’s research partner in Canada, on bench scale models of commercial units. The trials were highly successful in purifying spherical graphite to levels ranging from 99.93% Cg to 99.99% Cg. The requirements of battery manufacturers vary in particle size and purity with the latter specification usually being in the 99.9 to 99.95% Cg range. Large flake graphite was purified to levels ranging from 99.73 to 99.83%Cg with further improvements possible.
