Here he speaks to
The Gold Report's sister title,
The Mining Report, about how China's geology, cost structure and disregard for environmental degradation have led to rare earth world domination. But the landscape is changing...
The Mining Report: Jack, as we move into the age of technology metals, what is the current state of the rare earths sector inside and outside of China?
Jack Lifton: The rare earth elements (REE) are not rare in the common sense of the word. It's that they're rarely produced because of production costs. Rare earths typically are present in small proportions to what is otherwise being mined; they are almost universally byproducts. This presents a very high cost picture for developing an REE "mine."
Processing REEs is another impediment to their development. The traditional processing technique for separating REEs from each other and purifying them hasn't evolved very much over the last century. It's gotten a little easier, but it remains very slow and very expensive.
The idea of building a very expensive mine coupled with a very expensive separation plant has put an economic burden on the development of rare earth sources, at least outside of China, in the last 10 years. Very little thought went into the REE boom that began around 2007. Nobody asked what was the point. What were we going to produce that was in short supply? The excitement of the venture took over.
In 2011, the Chinese ministry put out a notice saying that it was considering a halt of HREE exports. Suddenly, the sky was falling. China was going to stop exporting HREEs. That will kill our industry, destroy our military and life as we know it. What actually happened was that the Chinese ministry in charge of setting goals for industries backed off. It didn't stop exports, but it did tighten up the export controls and reduced the quotas.
You have to understand that the Chinese don't think about North America, Australia or Europe as competitors in the REE sector. In August, I attended a meeting in China where the chairman of Baotou Steel Rare Earth, whose Baosteel division produces LREEs in Inner Mongolia, declared his company the world's largest LREE producer and the largest vertically integrated company in the REE sector. In effect, he was saying, we produce so much of this stuff we don't even know what to do with it.
He announced Baotou would produce a minimum of 30,000 tons of surplus cerium this year. I understand that because you have to produce all of the rare earths to get any of them, but my question was why? The answer was the 15% of Baotou's deposit that's neodymium and praseodymium, the magnet metals. That is really what Baotou is after. The Chinese just keep producing and stockpiling the other stuff to get at the critical magnet material they need.
No matter how you figure it, there isn't enough of the magnet metals to meet actual demand, never mind projected demand. China isn't producing enough neodymium and praseodymium to meet its own internal demand. One way to augment production is to start producing LREEs, which are 85% stuff you don't need, to increase the production of the 15% you do need. That seemed to be what the Baotou chairman was saying. I came back thinking that the last business I want to be in is one that depends on a revenue stream from LREEs, which are being produced in surplus in China.
TMR: Is there still demand for HREEs outside China?
Jack Lifton: Yes, of course. The point is China is still the only HREE producer because of the cost structure. Heavy rare earths occur almost everywhere in the world in extremely low-grade deposits. In China, for example, HREEs come from the so-called ionic adsorption clays, which are just a few hundred parts per million. Now luckily for the Chinese, mining ionic adsorption clays is not nearly as expensive as underground or even surface mining of hard rock material.
For example, if I have 50 parts per million of dysprosium in ionic adsorption clays, I need to process 1 million tons of clay to get 50 tons of dysprosium. By comparison, if I move 1 Mt of rock at Mountain Pass, California, I will produce 50-80,000 of REEs. In China, I'm going to get 50 tons of dysprosium. The Chinese do this on an immense scale, producing as much as 15,000 of these materials, of which only 8-10,000 tons are the REE-related element yttrium. The Chinese are washing millions and millions of tons of clay.
China is the only place that produces HREEs from ionic adsorption clays. That happened as dysprosium-modified magnets became extremely useful and necessary.
TMR: Is that due to demand for permanent magnets for electric cars?
Jack Lifton: Right. Magnets used in extreme environments of hot and cold need to be modified with dysprosium and terbium so that they don't permanently lose their magnetization when they go through a heat cycle.
Quite frankly, if these elements had been found anywhere else in the world, they probably wouldn't have been developed. The world is fortunate that they were found in such a low labor cost, but highly developed country.
Ionic adsorption clays exist in Vietnam, Thailand, Cambodia, Indonesia, Malaysia. They haven't been developed there for many reasons. Some are ethical reasons. Ionic adsorption clay mining is extremely dirty environmentally and very difficult to contain.
A significant source of this material was discovered in Thailand right under a resort area a couple of years ago. The Thai government said it didn't give a damn what anybody thought, nobody was going to start ionic adsorption clay processing next to the swimming pool in a country where tourism is the number one revenue source.
The Vietnamese have a wide variety of rare earth sources, hard rock, as well as ionic adsorption clay, but dealing with the country has been impossible so far.
TMR: You've mentioned that the cost of processing may be going down. Will that make HREE mining outside of China more practical?
Jack Lifton: Yes and no. Yes, if somebody creates a central processing facility. Outside of China, I've been counseling people not to commit to building a solvent extraction plant until they've looked at the other technologies that are available. The impediment is that none of the other technologies has been operated at scale. However, pilot plants are underway in North America and Europe for at least two non-solvent extraction technologies.
TMR: Is there any hope for extra-Chinese companies if they can utilize shared processing at lower costs?
Jack Lifton: If these materials are critical for our military and our lifestyle, somebody will have to capitalize security and independence. Geography is destiny in geology. The Chinese have these materials. They don't have to pay to develop mines or develop new ways to separate the material.
The only thing that's impeding China is its own internal inflation, its cost of labor and chemicals, its skilled labor. These are going up all of the time. Now, China is looking for REE sources elsewhere in the world.
Isn't this the ideal situation in a capitalist system? We have somebody who wants something we've got. Why aren't we developing it?
TMR: Any closing thoughts?
Jack Lifton: In the West, our cowboy capitalism is looking for new ways to apply existing technology to REE separation. A genuine change in how REEs are processed may be the salvation of the non-Chinese industry. It costs a bundle to build a mine and processing plant – amounts of money the market cannot support because there isn't enough profit to be made to repay the debt. It's way too late to raise that amount of equity.
I'm advising the industry to look at processing together because there still wouldn't be enough material to meet existing demand. If you built a central processing plant in North America and that cost were taken off the business model, that might help convince investors to fund one or all of them. We need all of them.
TMR: Thanks for your time and your insights.
