Ann: Licensing Agreement for Downstream Purification Process, page-99

Dorfner had a minimal acid consumption flow process running in June 2017 (therefore possibly developed way earlier) == https://blackrockmining.com.au/wp-content/uploads/070617-BKT-achieves-industry-leading-spheronising-graphite-yields.pdf

RNU developed stages of low temp roasting w/ caustic solution, followed by multi stage leaching resulting in HF free (ann dated 10/08/2023). I asume these stages replace certain blocks within Dorfner's flow process but these stages are also specific to a given graphite deposit as RNU has previously stated.

If one flow process (Dorfner/RNU) produces 99.99% carbon purity vs 99.97% carbon purity (EGR) - can't be the same process as it is producing a higher carbon purity. Thankfully DC is a lawyer by trade
