I would like to expand a bit on it
They would have to use acid leach , maybe many times, which would be very costly and also have environmental issues.
I do not see were they say anything about their process being environmentally friendly?
I see were they say it is more environmentally friendly than the chinese process but what does this mean? Not as much Acid?
"Almost all natural spherical graphite is currently produced in China and purified using strong acids which results in large volumes of acidic and toxic waste. Thermal purification at temperatures as high as 2,400 C can be used but it is expensive in terms of capital and operating costs. 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"
They later say " purified in an environmentally sustainable manner"
Gold mines do theirs in a environmentally sustainable manner too,,,lol
Big difference compared to ZEN's process "simple caustic baking leach process conclusively demonstrated that an ultra-high purity graphite product with >99.97% Carbon (“C”) can be produced from the Albany graphite deposit. The process was successfully applied to a variety of graphite concentrate samples that had initial carbon grades in the range of 46 – 90% using conventional flotation techniques. In all trials the final purity values were >99.97% C and up to 99.99% C in many cases, regardless of initial carbon grades"
For NGC, if it was cheap and environmentally safe, they would come out and say it, not dance around with words IMO.
Take Care
