Aubrey Eveleigh and His Use of Caustic Bake...I don't care what you say you are Hoov, you're just another Anonymous poster here who seems to like to throw things around and manipulate what was posted earlier to suit your agenda.
Roasting or using heat was never insinuated as that surely would raise costs, whether you know anything about chemistry or not. Read the past promotional literature and you'll see that Caustic Bake was used, no mention of external heat sources, and no mixing of the grams of ore/slurry used either.
Notice, I"m using grams. Even a 5 tonne mini bulk sample is small in terms of ore. They'll need testing on 100's of tonnes using a pilot plant to truly get an idea of costs and beneficiation potential.
Just so readers can judge for themselve how manipulative you and the Boyz from TCC can be, I'll provide links as to the Caustic Bake and no mixing of the slurry using only NaOh, which by itself should create heat when mixed, but on a commercial scale may just not provide the heat needed to purify the graphite to the 99.99% level that it did on a bench scale level in the lab.

Notice how Aubrey says he's confirmed the caustic bake process through an unamed 3rd party? Good way to not being held responsible for such claims isn't it? lol

GIN: You say that the vein is ultra-high purity at 99.96-percent carbon, but the drill results only show 5 to 7 percent carbon; how do you account for that discrepancy?
AE: It’s not a discrepancy. When you drill and you test for the grade, it comes out at 5 percent because what you’re testing is all the material in here. You cut it, you sample it, you send it in for analysis and you’re also diluting it with the granitic clasts that are in the breccia pipe. The key is not the grade on the front end, it’s the purity on the back end. When we put that through a metallurgical test, and we’ve done this on several occasions at SGS Lakefield, we put in the 5-percent grade, we grind and we do a flotation and a caustic bake. A caustic bake is sodium hydroxide. It’s not an acid as some people are suggesting; it’s sodium hydroxide, 25 percent by weight, and we can recycle that material. After you go through that process it comes out at 99.99 percent. What I’ve been told is that we’re the only company globally that can use caustic bake to get to 99.99 percent. I’m getting it third hand from a good source and we haven’t confirmed that, but I’ve been told that.
GIN: I’ve been told by geologists that graphite can be easily purified using acid leaching. Is that not true?
AE: Yes. You can upgrade flake thermally and with acid. It’s a little more expensive. When somebody says that they can do that I would simply ask, “what is the cost?” We know from our processing that we can do it with a caustic bake fairly cheaply.
For the laymen, like myself, here's a video that demonstrates how NaOH reacts without heating on a small scale, similar to a bench scale, no, lol. But of course on a much larger scale, heating or roasting would be needed. JMO
