Transcript: How This Tech Can Break China’s Rare Earth Monopoly: Dr. James Tour

Here is the full transcript of synthetic chemist and nanotechnologist James Tour’s interview on American Thought Leaders with host Jan Jekielek on “How This Tech Can Break China’s Rare Earth Monopoly”, Premiered November 23, 2025.

Interview Begins

JAN JEKIELEK: This is American Thought Leaders, and I’m Jan Jekielek. Jim Tour, such a pleasure to have you on American Thought Leaders.

DR. JAMES TOUR: Thank you for having me.

China’s Rare Earth Export Controls

JAN JEKIELEK: So recently the Chinese Communist Party basically put unprecedented export controls on rare earths, frankly affecting the whole western world. There was a deal reached. There seems to be some backtracking since. What were you thinking when you saw this?

DR. JAMES TOUR: Well, it’s not just rare earths, it’s a number of other metals too, now calling them critical metals. So it’s copper, it’s indium, gallium, tantalum, antimony, and several others.

We turned over manufacturing to them over the last 30 years. And so we have very little capability to manufacture these metals in the US. And a lot of times if they’re mined here, they’ll go to China for processing. So we don’t have the capability to take the ores and to turn them into the base metals that we can use.

It’s a big problem. We wouldn’t be able to build electric vehicles here. This would shut down our manufacturing of our automobiles. It’s over. This would shut down our Intel plants, our chip manufacturing. So it’s a very big deal. And even just the threat of it shakes up the markets.

JAN JEKIELEK: And now you’re working on technology that’s directly related to this issue?

DR. JAMES TOUR: Yes.

JAN JEKIELEK: So explain that to me.

Flash Joule Heating Technology

DR. JAMES TOUR: We developed a technology in my group called flash joule heating. And it’s not a name that we coined, that’s been around where you put a high voltage and a high current through a material that is not highly conductive, that has about a one ohm resistance, which means that you can conduct electricity through it.

It’s much like your toaster. Your toaster, you have this coil that you put a voltage across it and you run this current through. But there’s enough resistance. That coil gets red hot very quickly. That’s flash joule heating. And it’s like the old incandescent light bulbs. And you see this big glow.

And what we learned is that we can put any carbon material between electrodes and flash joule heat it, turn it into graphene. Graphene is a space age material. And we started a company around that that’s up and going.

But then we realized that we could take certain materials, say industrial waste, like fly ash, which is the residue that’s left over after burning coal, the inorganic material. We could flash it and we could get rare earth elements to come out. And so we could do that. We get other metals from industrial waste and then also consumer waste, consumer electronics.

And you can put a high voltage, high current. And then we learned if you put chlorine in during the process, then they come out much more easily because you convert them from metal zero or metal oxides to metal chlorides, which are much more volatile. You lower the boiling point by 3,000 degrees and then they’ll come out.

And just based on the reactivity of a certain metal to chlorine at these higher temperatures, we can predict when they’re going to come out, and we can separate them coming out. So we developed this technology, we started doing this in 2020. We started doing this on metals.

And then it was after that that the metals that China put this kibosh on, sending us metals. And it became much more important. So I found myself in this very important area.

How the Process Works

JAN JEKIELEK: Okay, so let me get this straight. You’re taking electronic waste or tailings or something like this. You’re putting them between two plates. You’re putting a massive amount of current through it. Wait, you’re adding chlorine to lower the temperature that you do to get them this red hot, to separate everything out, and then you’re somehow collecting each metal chloride as it basically distills out. Do I understand it right?

DR. JAMES TOUR: You have it right. So what happens is when the chlorine comes in at these high temperatures, the chlorine will react with the metal oxides or the metal zero. By metal zero, I mean the base metal. You can have a metal oxide or a base metal and it will make the metal chloride and then the metal chlorides distill out.

And the thing we control is at what temperature are we heating this to react with the chlorine? And then at what temperature are we distilling it out? And based on those two parameters, we can separate. We can pull out one metal and then the next and the next and the next. So that’s right. It’s really that simple. It’s a very simple operation.

Now remember the rare earth elements, right? Now the plants that are separating rare earth elements are 500 meters long, is their process. Now it won’t be a building that long, you know, snake back and forth, but it has to traverse that long. This is much shorter, much shorter. And it will do it much faster than what’s traditionally used.

And we’re not bringing it through in water or acids, none of that. It’s just through this flashing process. So it’s much cleaner and much faster.

As you know, most wars are fought over resources. Water, oil, minerals. People fight over this and they kill each other over this. So when I was presenting this to a group of generals from NATO, and the head guy there, he stood up, he says, “This is going to prevent wars.” He says, “I don’t have to fight for this.
