Ann: 99.9995% Purity Confirms Battery and Downstream Suitability, page-2

A sample of Malingunde raw graphite concentrate (mine gate product) was purified using a GTL proprietary low temperature thermal purification process. “Low temperature” is defined as a process that runs at less than 2,100°C and is facilitated with very mild addition of chlorine gas. The majority of thermal purification processes in the graphite industry sector are performed at temperatures of 2,700°C to 3,000°C, which require very high energy input and add significant costs, as well as generate a notably higher CO2 footprint.
