Has Chemist Cracked America’s Rare Earth Supply Problem?

Excerpt:
"One flash is all it takes.

That’s how James Tour believes America can tackle China’s rare earth dominance.

All he needs is discarded electronics—of which the United States has mountains. And from these scraps, the Rice University chemist and nanotechnologist has pioneered a way to quickly extract rare earth metals.

“We can pull out one metal and then the next,” he told The Epoch Times. “It’s really that simple.”

Tour’s solution is flash Joule heating: rapidly heating up the materials to thousands of degrees to vaporize the metals. Mixed with chlorine gas, the vapors turn into chlorides that emerge at different temperatures."

    On the Chinese companies: I read somewhere that every corporation in China is owned at least 51% by the CCP, which gives the Party a controlling interest in everything they do. Add to that - Bill Clinton gave China the "Most Favored Nation" status back in about 1995, putting China on an even legal footing with all of our actual allies - Japan, Germany, France, the UK...
    This NEVER should have happened, and has led to the trade imbalances and Chinese monopolization of industries, ever since.
    With those two issues, the US is screwed.
    Maybe Trump can put us back on an even keel, but he's working against not individual companies, but the entire God-damned CCP.

    Is everyone clear on what "rare earth" means? Those elements are common but widely dispersed and are difficult to separate from each other.

    According to Wikipedia, "The term "rare-earth" is a misnomer, because they are not actually scarce, but because they are found only in compounds, not as pure metals, and are difficult to isolate and purify."

    Exactly! Manufacturers might set up returns to their recycling centers so they can add to their profit.
    I probably have a couple dozen old pc boards lying around here.

    Also, keep in mind. Most machines are 3-5 year lifespans. While you are setting this up, get some "Electronic Recycling" Process going. So that 50% of your supply comes from recycling recently departed equipment, and 50% from the backlog.

    The question really becomes... How fast will we run out of the oldest stuff?

    I am reminded that you can have a LOT of "garbage" of some type (Kudzu). But the minute someone figures out how to run a CAR on it. You will have shortages! LOL

    Should help a lot! Saw this the other day, from Epoch I think.
    Nitron magnetics is working pretty hard to make rare earths irrelevant in magnets. Their magnets are in production, but small. They have issues with size, and larger magents have to be bonded, losing a portion of their properties. We are working with them on proper motor/generator designs to leverage them.

    Sounds like a process very similar to oil refining.

    " isn't that mountain scattered all over the land"
    I agree that there would be a significant up front cost, but wouldn't that be considerably lower cost than mining half a mile or more below the surface in Yak-istan?
    Adding 'computer' trash to recycling process now will give would result in a new surface 'mine' and constant stream for the future to feed this process.
    How many million people have old non-working electronics in their closets today?

    In the end, aren't all Chinese companies fronts for the CCP? No mystery that selling an American company to a Chinese company would mean eventually shipping it and it's technology to China. "Partnering" an American company to a Chinese company does the same thing except bleeding all the wealth out of the American side to the Chinese "partner" precedes the move. Trump is the first politician in my life time to say "No more!".

    The article says America has a mountain of discarded electronics, but isn't that mountain scattered all over the land, which would add to the expense of recovering the metals?
