It's funny how you continuously undermine C.Freys experience in this field...I'm sure you are aware of his background, but just in case:
http://www.pro-graphite.com/home-en
...and his website does not include his hands-on experience in actual graphite mines.
There is so much info in his announcement and it clearly explains what methodical process is being undertaken in Germany to prepare the 8 different samples.
Mixing and Cross contamination is not an issue as the plan is to provide 'Spherical Graphite Commercial Plant's' directly to end users or Graphite Miners which will allow them to supply Anode Manufactures with their required characteristics and with the big difference compared to current process by using EcoGraf ie more cost effective and significantly less harmful to the environment.
The current exercise with those 8 different G deposits is to show end users which ones are suitable and what characteristics the end product will have by using EcoGraf.
Like I said, there is so much info in this announcement and should be read in full detail by all and I'm sure would have been of big interest to CBA when deciding to invest more in KNL, the last paragraph sums up the objective, just in case some don't like to read the full 2 pages
...Kibaran’s commercialization of EcoGraf is based on anode manufacturers’ plans to diversify future supply arrangements from their present reliance on Chinese battery graphite, that is produced using an environmentally harmful hydrofluoric acid purification process. Customer feedback on the process has been exceptionally positive and successful application of this eco-friendly process to other sources of natural flake graphite will provide an opportunity for the early start-up of battery (spherical) graphite facilities in Europe and Asia, in parallel with the development of the long life and scalable Epanko Graphite Project in Tanzania...
