meanwhile over at RNU they have just released an update on their battery anode material, of interest is this...

Purification circuit. The purification circuit is similarly being expanded to permit the processing
of increased volumes of Spherical Graphite that will pass through the downstream milling
circuit. Additional changes to the purification circuit include the incorporation of an optimised
purification flow-sheet. The original purification design, adopted in the 2019 Downstream PFS,
was based on performing a caustic roast, followed by a multi-step leaching process11.
Following optimisation trials on Siviour Spherical Graphite in 202112 and 2022, Renascor
modified the process design to commence with leaching, to be followed by a caustic roast and
a secondary leach. Renascor considers this updated design to offer better efficiencies in
meeting customer specifications and offer potential operating savings through lower water
usage.
