Ann: BKT World first Ultra High Grade Graphite from Pilot Plant, page-27

..."BKT is the only ASX Tanzanian graphite company i am personally aware of doing commercial scale tests. can you tell if if there are any other ASX Tanzanian graphite companies"...

And I thought you're up to date:

Flotation Tests Processing of the 200-tonne bulk sample through a commercial-scale plant returned results which replicated those of the Bankable Feasibility Study (BFS) pilot-scale testwork.

That was already a couple of years ago back in 2016, lot's of validation test work by end users since then.
