Canada Carbon (TSXV:CCB) has presented early results from its metallurgical upgrading program being conducted for its Miller hydrothermal lump/vein graphite. Preliminary results returned carbon purity as high as 99.9942 percent using standard caustic bake upgrading.
As quoted in the press release:
One 2 kilogram (“kg”) flotation concentrate sample was randomly selected from the pilot plant concentrate products and was assessed for carbon purity by Glow Discharge Mass Spectrometry (“GDMS”), both before and after the graphite concentrate was upgraded using the SGS standard caustic bake process. The pre- and post-treatment sample was fractionated into five particle size classes, representing 100% of the sampled flotation concentrate. Carbon purity as high as 99.9942% was reported by Evans Analytical (Liverpool, NY) for specific size fractions of the caustic baked material, using the GDMS method. The mass-weighted average carbon purity for the entire sample was 99.9925%. The Equivalent Boron Content (“EBC”) was calculated using the GDMS results, with individual size fractions delivering EBC as low as 0.720 parts per million (“ppm”).
Canada Carbon executive chairman and CEO, Bruce Duncan, said:
I would like to emphasize that these results are preliminary, in that further optimization of the caustic bake technique is contemplated. We have also begun the process of assessing the upgrading of our Miller hydrothermal lump-vein graphite by another industry-standard technique. Those results will be reported, when received. The Miller HLV graphite continues to exceed our expectations. Even our smallest graphite particles can be easily upgraded to meet the nuclear purity standard. The Miller HLV graphite’s high crystallinity and purity set us apart from any other natural graphite.
