sure, but it should be clear that the 3 projects (HEG, ATC and HEG) arent easy to compare under that circumstance.
furthermore, within the study GR engineering did make the statement that the capex includes an EPC (fixed price+ramp up garanty) contract. so it seems to be definit (for the moment) that the production line wont be extented respectively upgraded with a finishing line.
according to the end product specificies the productprices shouldnt depend only on the purity. at least its higly probable that you get a higher price for your product if its refined to powder or pellets. therefor its obviously appropriate to use a lower price of 24000 usd per ton of 4N HPA within the study.
