NGC - Also The Proprietary Purification Process Fo NGC - Also The Proprietary Purification Process For Spherical Graphite
The proprietary purification technology developed by Northern and its metallurgical research partners is much more environmentally friendly than the Chinese approach and operates at significantly lower temperatures than traditional thermal methods. It also involves relatively low retention times in the furnace and will likely be a continuous rather than a batch process. As a result, costs should be significantly lower.
Hazen Research is currently purifying larger quantities of spherical graphite to provide potential strategic partners in the battery industry with samples made from Bissett Creek ore that has been processed using Northern's commercial mill flow sheet and purified in an environmentally sustainable manner. It has already been successfully tested in batteries at the National Research Council of Canada.
