I think the flake basket is important. Smaller flake (100 mesh) is better suited to battery anode production as it needs less milling to produce PSG, compared to large flake. Large flake currently commands a higher price as it's better suited to other uses such as a lining crucibles for steel production. However, given the growing demand for lithium ion batteries, I think that will flip in the coming years with the price for small flake surpassing large. From what I recall, RNU is blessed with a good basket for anode (high proportion of small flake). Just my opinion.
