Physically, rare earths are not scarce. They are even more common in the earth’s crust than many other metals such as gold, uranium, or tin. However, they are considered rare because their mineable concentrations are less common than for most other ores.
What country has the most rare earth minerals?
China
1. China. Unsurprisingly, China has the highest reserves of rare earth minerals at 44 million MT. The country was also the world’s leading rare earths producer in 2020 by a long shot, putting out 140,000 MT.
What can replace rare earth metals?

| Yttrium | Samarium | Erbium |
| Lanthanum | Europium | Thulium |
| Cerium | Gadolinium | Ytterbium |
| Praseodymium | Terbium | Lutetium |
What minerals are in short supply?
The amounts of lithium, cobalt, graphene, indium and other critical minerals needed for low-carbon technologies alone are expected to increase anywhere from 100% to 1,000% by 2050.
Are rare earth elements currently being mined in the United States?
Currently, US companies get the vast majority of their rare earth materials and magnets from China.” The Mountain Pass mine in California, controlled by MP Materials Corp, is the only active rare earths mine in the United States.
Why does China have a monopoly on rare earths?
China leveraged its lax environmental laws by way of an indirect ecological subsidy in the rare metal industry. However, the turning point came in 2010 when the world realised that China had a crippling monopoly where it could punish any country by controlling the supply of the rare earth metals.
Does South Africa have rare earth minerals?

Does Tesla use rare earth metals?
Tesla started in 2019 to combine engine types. Its S and X models have two motors: one with rare earth magnets, one without. The induction motor provides more power, while the one with permanent magnets is more efficient, Tesla said: Including a rare earth motor boosted the models’ driving range by 10%.
What’s the rarest metal on earth?
francium
The rarest metal on earth is actually francium, but because this unstable element has a half life of a mere 22 minutes, it has no practical use.
Are we running out of rare earth metals?
The reserves of some rare earth minerals used in electronics, medical equipment and renewable energy could run out in less than 100 years. Rare earth minerals are naturally occurring resources, which cannot be recreated or replaced. Some are present in only very small quantities in the Earth’s crust.
Why is there a chip shortage?
How the shortage began. Computer chips started becoming scarce early in the pandemic, when chip buyers, in particular automakers, slashed their orders fearing a global recession. In response, semiconductor plants reduced their production. An increase in demand.
What materials are becoming scarce?
Here are six already under severe pressure from current rates of consumption:
- Water. Freshwater only makes 2.5% of the total volume of the world’s water, which is about 35 million km3.
- Oil. The fear of reaching peak oil continues to haunt the oil industry.
- Natural gas.
- Phosphorus.
- Coal.
- Rare earth elements.
Why are there metal shortages?
The Covid-19 pandemic threw supply chains into chaos, and steel — an essential metal used in everything from dishwashers to cars — was not immune to these disruptions.
Is rare earth a good investment?
Despite their abundance, rare earth metals are valuable because they are hard to get, and they are in high demand. Investors can gain exposure to rare earth metals through exploration and processing companies, such as Neo Performance Materials (TSX: NEO) and Freeport-McMoRan (FCX).
What is the largest rare earth mine in the world?
Bayan Obo mine
The Bayan Obo mine in Inner Mongolia, China is the world’s biggest rare earth mine. China is the biggest producer of the rare earth elements in the world.
Is lithium a rare earth?
A lot of these warnings have been incorrectly categorized under “EVs and rare earth metals.” Though neither lithium nor cobalt are rare earth metals, and rare earth metals aren’t nearly as rare as precious metals like gold, platinum, and palladium, there are important issues surrounding the production of lithium-ion
Does Russia have rare earth minerals?
As of June 2019, Russia held the fourth largest reserves of rare earth minerals in the world at 12 million tons. That puts it way above Australia and the United States. Those nations hold 3.4m tons and 1.4m tons respectively.
Is Ethiopia rare earth minerals?
The Kenticha mine ranks as the world’s sixth-biggest miner of tantalum, while EMDSC is Ethiopia’s only commercial producer of the rare earths metal.
What minerals are only found in China?
With the exception of nickel, chromium, and cobalt, China is well supplied with ferroalloys and manganese. Reserves of tungsten are also known to be fairly large. Copper resources are moderate, and high-quality ore is present only in a few deposits.
Which African country has the most rare earth metals?
Africa offers the greatest potential for rare earth production, especially in South Africa, Tanzania, Malawi and Mozambique. Kenya, Burundi, Zambia and Namibia are also mentioned. Six of the world’s top 10 cobalt mines are in the DRC.
Which African country extracts the most rare metals?
The Great Western Minerals Group’s Steenkampskraal project in South Africa has some of the highest concentrations of certain types of rare earths of any mine outside of China.
