I have worked with the Chinese REE industry, and we've often bumped heads and shared ideas together with them and I can confidently tell you, the Chinese don't use anything novel that has not been established in Western science already. What they do have is executing rarely-used techniques confidently at scale, but all of that is already often published in the West. The only reason the West hasn't done it is because…
What I mean is that since the peak of American REE in the 1970s and 1980s(?) a lot of the engineers who have working knowledge are retired. There's nothing theoretical we can't dig up but I think there will need to be a number of years for the US to catch up in terms of craft knowledge or "metis" (as Dan Wang likes to call it) and processing equipment and plants. Maybe I'm wrong. I gained my knowledge second-hand/thi…
The real barriers are talent and the regulation vs profit motive balance. What I mentioned in my previous comment was effectively an effect of the intersection of the two - you can't find novel ways of processing harmful substances without having the technical talent to find these out in the first place, nor without giving them a free reign after deprioritizing profit.
Let's take arsenic for instance, a substance that's a harmful byproduct arising out of most mining operations. We already have the technology in the West to lock away arsenic into glass, but a.) apart from the big ones, most companies are unaware of them, and b.) even if they were aware of it, the tech is a significant line item that shies investors and companies away from investing into it.
> What is your estimate on how long it would take the West to catch to at least supply some of the rare earth components and what the real barriers might be?
Never. Yes, there are a few companies still engaged in trying to secure REE supply (Glencore being the most notable), but due to Western regulatory and policy limbo, the answer is never. For this to change, you need regulators open to experimentations and a concerted effort by the government in trying to reestablish REE independence, both in extraction and in processing, but I have yet to see either happening. It's telling when frankly the US is the country in the West most likely to catch up still, but the gap is deeper than the Darien Gap .
