Still thinking about this as it will be probably one of the most important parts of the BSX story in years to come.
The process flow to produce Nickel & Cobalt Sulphate.
Knowing that BHP patented the Nickel Sulfate Powder process, went on to build & commission a plant & signed an offtake with Tesla for around 100ktpa of the powder, I'm very interested in whether Blackstone have drawn on a particular process flow sheet from existing Australian patents which are as per the the list below this graphic from IGO....
two patent searches conducted - Nickel Sulfate & Nickel Sulphate
Companies are JGC, BRIMM, Sumitomo, BHP, IGO & Solvay.
Doubtful the company would respond, so has anyone looked at this before - noting IGO have publicly included Wyloo (FFI/Fortescue) in the above.
But if there is a technology share with BSX, I'd be interested to know who.
Of course I have a theory on who would make the most sense but it is likely to be way off the mark.
