The Company is testing its high purity graphite concentrates at independent test facilities in Europe, Japan and the USA.
Spherical graphite has been produced from early generation 95.86% TGC concentrates. These concentrates easily made 99.98% purity spherical graphite from conventional milling, spheronising and purification processes.
Current spherical testing is with 99.2% TGC concentrates, which are expected to produce higher specification end products and minimise acid consumption at the purification stage. Our ambition is to eventually replace the commonly used acid purification step with an environmentally cleaner process.
