Thanks, Donkey Dick!
I reckon its fair to say that the lower purity (cheaper) feedstock can be used towards the first product type from what we can consider the basic processing procedure (give or take additional steps to increase purity where needed for customer product specs):-
Then the premium Expanded Material of the highest purity and maximum expansion possible, probably requires starting with more costly high grade carbon feedstock. This involves any one or more of the (seven) different processing steps. I wonder whether the PGT team have already achieved this during the commissioning phase with samples sent off to prospective clients (namely in the US and Japan)? And, now its back to basic "Expandable" Graphite Material production for the rest of the year to meet our binding offtake obligations... until we score additional BOAs for the more lucrative product which would bump up our output, sales and profit margins.
