1. Understanding Rare Earth Elements

Definition and Classification: Gary begins by defining rare earth elements (REEs), clarifying common misconceptions about their rarity. Contrary to popular belief, most REEs are not exceedingly rare in the Earth's crust. There are 17 rare earth elements, comprising two light elements—scandium and yttrium—paired with the 15 lanthanides: lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium. He humorously nods to the complexity of their names, praising Tom Lehrer for making the list memorable (05:45).

Physical Characteristics: These elements are typically soft, silvery metals with considerable weight. While most REEs aren't encountered daily, their significance escalates when considering their applications in various technologies.

2. Historical Significance of Rare Earth Elements

Pre-1965 Status: Before 1965, rare earth elements held minimal economic value and were considered more of a scientific curiosity than a commercial commodity. Extraction was primarily based in easily mineable sands in India and Brazil, with limited global production centered around the Steenkampskraal mine in South Africa during the 1950s.

The Color Television Boom (1965): A pivotal moment for REEs occurred in 1965 with the advent of color television. The element europium became crucial for producing vibrant colors in TV screens, sparking a surge in demand. A discovery at a California mine increased europium content from 0.05% to 0.1%, significantly enhancing supply (12:15).

Neodymium Magnets and Technological Expansion: In 1984, General Motors discovered neodymium magnets, the strongest commercially available natural magnets. These magnets revolutionized various industries by allowing for stronger magnetism in smaller sizes, leading to widespread applications in electronics, automotive, and renewable energy sectors (18:30).

3. The Modern Importance of Rare Earth Elements

Ubiquity in Technology: Gary emphasizes that almost every modern technological device incorporates REEs. From computer chips and fiber optic cables to smartphones, MRI machines, and electric motors, these elements are foundational to the functionality and advancement of contemporary technology (22:10).

Economic Impact: The importance of rare earth elements extends beyond technology, influencing international trade and geopolitics. Their critical role in military equipment, renewable energy technologies, and consumer electronics makes them a strategic asset for nations worldwide (25:50).

---

4. Global Production and China's Dominance

China's Strategic Position: In the late 20th century, Chinese leader Deng Xiaoping prioritized the production and processing of REEs, foreseeing their rising demand. By the 1990s, China's production surged dramatically, capturing over 97% of the global market by 2010. This dominance was not solely due to abundant reserves—China holds about a third—but also because of competitive pricing that undercut other producers, leading to the bankruptcy of non-Chinese mines like California's Mountain Pass (35:20).

Production Dynamics: Global production of rare earth elements nearly doubled by 2010, though China's output plateaued, allowing other countries to ramp up their production. Despite China's continued lead, nations such as the United States, Australia, Canada, and South Africa have been actively exploring and developing their own rare earth deposits to mitigate dependence (40:45).

---

5. Future Demand and Challenges

Increasing Necessity: The demand for rare earth elements is projected to surge with the expansion of electric vehicles, renewable energy infrastructure, and emerging technologies like nuclear fusion reactors. For example, an electric car like the Toyota Prius contains approximately 25 pounds (10 kilograms) of lanthanum for its battery and motor systems (45:00).

Supply Constraints: While the world is not on the brink of depleting REE reserves, the geopolitical concentration of supply poses significant risks. Ensuring a stable and diversified supply chain is critical for technological and economic stability.

---

6. Mitigation Strategies and Innovations

Recycling Efforts: Gary highlights ongoing initiatives to recycle rare earth elements from decommissioned electronics and electric vehicles. Since REEs are elements, they can be efficiently recycled, which will become increasingly important as more products reach the end of their lifecycle (50:15).

Alternative Technologies: Researchers and companies are exploring technologies to reduce or eliminate the need for certain rare earths. While complete elimination is challenging, advancements aim to minimize dependency and find substitute materials where possible (53:40).

Exploration and Mining Innovations: Countries are intensifying their search for new rare earth deposits. However, mining REEs is complex, as these elements are not easily visible on the surface. High-quality deposits, like the one in China with 0.2% europium, are rare and require advanced extraction techniques. Notable discoveries, such as the 2011 find in Afghanistan, remain untapped due to geopolitical and logistical challenges (58:30).

Future Horizons: Looking further ahead, Gary speculates on the potential of extracting rare earth elements from extraterrestrial sources like asteroids and the Moon. Although currently speculative, such ventures could provide substantial new supplies if technological and economic barriers are overcome (1:02:10).

7. Strategic Reserves and Military Importance

Stockpiling Efforts: Recognizing the strategic importance of REEs, the United States military has embarked on stockpiling efforts to secure reserves. Initiatives include reopening the Mountain Pass mine and enhancing recycling programs to ensure a steady supply for defense and other critical applications (1:05:50).

See Mint Mobile for details. So let's start out with the fundamentals. What is a rare earth element? There are 17 rare earth elements on the periodic table. The two lightest are scandium and yttrium, which are located in the third period or the third column of the periodic table. The other 15 are the lanthanide elements. If you've looked at a periodic table, you might remember that there's a section of elements that are separated from the rest and form two rows at the bottom. The lanthanides are the top row of those two rows. The 15 lanthanide elements are lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thuleum, ytterbium, and lutetium. And I just want to say that after reading that list, my hat goes off to Tom Lehrer. So I think it's fair to say that for the most part, none of us deal with these elements on a daily basis. They're all soft, silvery metals that are rather heavy. However, I don't want to get into a chemistry analysis of each element because that would be painfully boring and most of you would wind up pouring wax in your ears. I will just add as a fun fact that four of those 17 elements are named after the tiny village of Itterby in Sweden. What's really interesting about rare earth elements is their importance in the world economy, because they are really, really important. If you remember back to my previous episodes on specific elements in the periodic table, most elements were discovered in the 19th and early 20th centuries. It became a lot easier once the periodic table of elements was set and it was possible to see where the holes were to fill them in. Here I should note that most of the rare earth elements are not, in fact, all that rare. To be sure, they aren't as common as iron or silicon, but most of them are on a par with other metals like tin or gold. The least common element is promethium, which actually is quite rare and radioactive. But the most common element is cerium, which is the 25th most common element in the Earth's crust. The rare earth elements weren't really that big of a deal prior to the year 1965. They were more of a curiosity, and they didn't have that much economic value. So what happened in 1965? And the answer is color television. It turned out that one of the key components for color TVs was the element Europium. As color TVs were a huge thing for TV manufacturers, there was suddenly a huge rush to find europium, the mineral monzonite would often have a europium content of about 0.05%. However, a location was discovered in California just over the border from Las Vegas, which had a europium content of a whopping 0.1%. Over the years, more and more uses were found for rare earth elements. One of the biggest uses was found in extremely strong natural magnets, in particular neodymium magnets. They were discovered in 1984 by General Motors and they are the strongest commercially available natural magnets that you can buy today. They can support thousands of times their own weight and have applications in whatever you can use magnets for. You can either get more magnetism for something the same size or the same amount of magnetism for something much smaller. Neodymium magnets are something you're probably familiar with, but the applications for rare earth elements are almost endless. Almost every technology product you can think of has at least some trace amounts of rare earth elements in them. Lasers, hard drives, MRI machines, batteries, high intensity lights, computer chips, fuel cells, nuclear reactors, LEDs, solar panels, wind turbines, jet engines, various military equipment, everything. Whatever you are listening to this podcast on right now has some rare earth elements in it, so it shouldn't be too difficult to see just how important these elements are to the world economy. No more rare earth elements, no more modern technology. So where do these rare earth elements come from? Before World War II, what little production of rare earth elements there was all came from easily mineable sands in India and Brazil. Because it was sand, it didn't require a huge operation to extract the ore, and there wasn't a lot of demand anyhow, so not much needed to be produced. Through Most of the 1950s, most of the world's production was located in a single location, the Steenkampskraal mine in South Africa. That shifted when the aforementioned Mountain Pass Mine opened in California. Again, this single mine was responsible for most of the rare earth mineral production in the world. For several years through the 1980s, the production of rare earth elements was rather low. In 1980, there was only about 30,000 metric tons of rare earth elements produced worldwide from mining operations, with about half that coming from the United States. Then, in the 1980s, Chinese leader Deng Xiaoping made what was, in hindsight, a brilliant decision. He made the production and processing of rare earth minerals a priority for China. As he noted in 1992, the Middle east has oil, China has rare earths. That there was going to be a massive increase in demand for rare earth elements was a pretty easy prediction. Even in the 80s and 90s more and more technologies were finding uses for rare earth elements. Chinese production began expanding dramatically throughout the 1990s, and US production began to decline. By 2010, worldwide production was at 130,000 metric tons per year, and China's share of the global market was over 97%. While China had a near monopoly in rare earth element production, it wasn't because China had all the rare earth elements. China certainly does have a lot of them, but it's estimated they only have about a third of the world's reserves. The reason why their share of the global market was so great had more to do with prices than with the number of rare earth elements available. China was able to undercut global prices, which drove many non Chinese producers bankrupt, including the Mountain Pass mine in California. However, global demand for rare earth metals hasn't decreased since 2010. Global production has almost doubled, but production in China has remained somewhat flat. They are still the largest producer in the world by a wide margin, but now other countries have been ramping up their own production. Demand for rare earth elements will probably increase even faster in the not so distant future. Electric cars are heavily dependent on rare earths. Electric motors require their use for magnets. A Toyota prius has about 25 pounds, or 10 kilograms of lanthanum. Likewise, generators and windmills need rare earth metals, as do solar panels and even the magnets in nuclear fusion reactors. While the world isn't running out of rare earth metals, many companies are working on alternative technologies which eliminate or reduce the amount of rare earth elements required. However, it's impossible to totally eliminate them. Likewise, nations are starting to explore for more rare earth elements. The United States, Australia, Canada, South Africa and many other countries have begun searching for more rare earth deposits. It can be difficult to do because you can't just look for ore sticking out of the ground like you might for other metals. The Mountain Pass mine in California was considered good because it had a whopping 0.1% Europium. And the best mine in the world is one in China, which has a whopping 0.2%. A massive find was made in Afghanistan back in 2011. But so far it hasn't been possible to begin mining. And it isn't even known if it will begin anytime soon. The United States military has been trying to stockpile strategic reserves of rare earth metals. It's been said the total U.S. reserves could fit in a suitcase. This has included reopening the Mountain Pass mine in California, which was mothballed in 2015. Another program has been increasing the recycling of rare earth metals. Because they're elements, they can be efficiently recycled. As old electric cars and other electronics become retired, this will become more and more important as it will recover more and more rare earth elements. In the very distant future, it might even be entirely possible to find some of these elements on asteroids or even on the moon. These strange elements with funny names have become vital to our modern world and will become even more important in the not so distant future. The elements, which were once novelties less than a century ago, now have become indispensable the Executive producer of Everything Everywhere Daily is Charles Daniel.
