The five rare earth metals are Dysprosium, Neodymium, Samarium, Europium, and Terbium. These metals, despite their name, are not particularly rare and are widely distributed in the Earth’s crust, but are difficult to extract and process due to their chemical properties.
Dysprosium, Neodymium and Samarium are predominantly valued for their magnetic properties and can be used to manufacture high-tech items such as smart phones, laptops and electric vehicles. Europium, on the other hand, is used extensively in televisions, microscopes and camera lenses due to its fluorescence properties, and Terbium is used to create color in televisions.
Despite their diverse uses, the rare earth metals have become increasingly important in recent years due to the demand for rare earth elements in the green revolution, such as their use in creating magnets for wind turbines and efficient electric car batteries.
Although the price of these metals have fluctuated over the years, their importance is only increasing as technology gets more and more advanced.

Why does China control rare earth metals?
China controls rare earth metals because they possess a large majority of the world’s supply. The country currently produces over 90% of the minerals, which gives them immense power as a global supplier.
Rare earth elements are used in a variety of important technologies, such as cell phones, wind turbines and electric cars, so having control over them has enabled China to dominate the electronics market.
In addition, these elements are vital for national defense and the Chinese economy is heavily dependent on their export revenue. China has used their control to limit the export of certain rare earth minerals to other countries, increasing prices and putting other nations at a disadvantage.
This has been met with criticism from other countries, but China shows no signs of relinquishing control over the metals.
Where do 98% of rare earth metals come from?
Approximately 98% of rare earth metals come from China, with the remaining 2% primarily coming from the United States, India, and Brazil. While there are other countries with more minor deposits, China is by far the largest producer of rare earth metals, helping to create the large majority of the global supply.
The production of rare earth metals in China largely began in the mid-2000s, and has since cemented the country’s position as the world’s top supplier. Large deposits of rare earth metals can be found in China’s Inner Mongolia autonomous region and have resulted in Chinese companies controlling almost the entire global market for rare earth materials.
How many rare earth metals are left?
Over 17 REEs have been identified, with some of the more common ones being yttrium, cerium, lanthanum, neodymium, promethium, and samarium. The amount of REEs in the earth’s crust or other locations is difficult to estimate accurately due to their rarity and widespread use in commercial and industrial products.
However, the amount of available REEs is diminishing due to increasing reliance on the elements for various commercial, industrial, and military applications. It is estimated that China, which currently accounts for around 70% of global REE production, could exhaust its supply of REEs by 2035, creating a potentially serious supply crisis for the rest of the world.
Furthermore, resource depletion is also exacerbated by the lack of economic incentives for exploration and extraction, as the current market for REEs is driven by Chinese production and not external demand.
Overall, there is no accurate way to define how many REEs are left, but it is clear that their availability is diminishing due to ever-increasing demand and resulting shortages due to natural resource depletion.
It is imperative that the world changes the current system of REE production and consumption so that we can survive the unavoidable depletion of REEs and maintain a steady supply for generations to come.
What are 5 rare minerals?
1. Grandiderite: Grandidierite is a rare mineral composed of the combination of magnesium, iron, and aluminum silicates. Only a few hundred examples of this rare mineral have been found, making it one of the most scarce minerals in the world.
Its main components are borosilicate, forsterite, and diopside, which makes it ideal for producing beautiful blue or green cabochons, with a silky sheen.
2. Jeremejevite: Jeremejevite is a rare mineral, composed of aluminum borate and it occurs in various shades of colorless, yellow, blue and pink. It is a form of boron mineral, which is found primarily in pegmatites, which are concentrated clusters of crystals and minerals.
It is often seen in jewellery pieces, and is highly valued due to its rarity.
3. Bastnaesite: Bastnaesite is a rare earth mineral composed of elements such as cerium, lanthanum, and yttrium. It is commonly found in carbonatite rocks and can also occur in hydrothermal veins. Due to its rarity, it is highly sought after for its low-temperature magnetic properties.
It is normally an opaque to translucent yellowish or greenish crystals.
4. Painite: Painite is the rarest mineral among gemstones, and it was discovered in 1951. Its unique color is the combined result of vanadium, iron, and manganese oxide in its structure. Painite can occur as yellowish-orange or brownish-red crystals.
It is valued for its beauty and rarity, as well as its ability to be transformed into beautiful jewellery or carvings.
5. Benitoite: Benitoite is a rare mineral composed of a combination of oxides including titanium, oxygen, and silicon. It is found exclusively in San Benito County, California. It is most known for its intense blue color, and is often set into jewellery such as rings, pendants and earrings.
Benitoite is the official gemstone of California, due to its rarity and stunning blue tone.
Which mineral is rare in the world?
Rhodium is one of the rarest minerals in the world. It is a silver-white metal which is a member of the platinum family. As of 2019, it is estimated that the global production of Rhodium is only about 20 tons per year.
Its rarity makes it a valuable precious metal with only about 1 part per billion of the Earth’s crust being composed of Rhodium. It is mostly used in electroplating and in the production of catalytic converters in vehicles due to its ability to oxidize pollutants.
It is also sometimes used in jewelry and in the production of extremely hard alloys. Other rare minerals include tantalum, beryllium, bismuth, and iridium.
Are we running out of rare earth minerals?
No, we are not running out of rare earth minerals, but it is becoming increasingly challenging to acquire them in large amounts. For one, rare earth deposits are scattered across the planet, not concentrated in one place.
Mining them from different locations can be difficult and expensive. Additionally, the concentration of rare earth elements in the earth’s crust is quite low. This means that only a very small percentage of the crust contains usable quantities of rare earths.
A third factor impacting the availability of rare earths is the strong demand for them. These minerals are essential components for many high-tech and green devices, such as computers, cell phones, wind turbines and solar cells.
The high demand for rare earths has lead to a modest increase in prices in recent years, further limiting the supply.
While rare earth minerals are not in danger of running out anytime soon, it is important that miners and government leaders take steps to ensure that these valuable resources are managed in an environmentally appropriate way.
Recycling programs, efficient extraction techniques, and responsible stewardship of existing deposits are all essential to preserving rare earth minerals and making them accessible in the long-term.
What country produces over 90% of all rare earth minerals?
China is by far the world’s leader in production of rare earth minerals, producing over 90% of the global supply. Rare earth minerals are important components in many high-tech products due to their unique properties and are used in a variety of applications, including magnets, batteries, and electronics.
China has a huge advantage in rare earth production due to its abundance of these minerals and thanks to government policies that make production and export of rare earth minerals easier. Other countries such as the United States, Russia, and India also have resources of rare earth minerals, but have not industrialized production as much as China.
Why are rare-earth metals so valuable?
Rare-earth metals are a group of 17 elements that are essential for many modern technologies, from smartphones to wind turbines and military equipment. They are also used in powerful magnets and lasers, as well as in medical applications.
The main reason why rare-earth metals are so valuable is their unique properties. They are malleable and possess a high electrical and thermal conductivity, making them highly useful for a variety of applications.
They also provide a superior strength-to-weight ratio compared to other metals, which makes them essential for use in the construction of strong, lightweight products. Plus, they are non-toxic and non-radioactive, meaning they are safe to use in a wide variety of products.
These rare-earth metals are also rare in nature; they make up just a small percentage of the Earth’s crust. As a result, they are in limited supply, making them a valuable commodity. This is especially true for some rare-earth metals like dysprosium, which is used in making lasers and magnets for military applications.
The rarity and usefulness of rare-earth metals lead to their high value. Companies and countries compete to get their hands on them, driving up the prices and making them some of the most valuable resources in the world.
