and the strong permanent magnets used in efficient generators and motors
Effective immediately, exporters of products containing Scandium, Dysprosium, Gadolinium, Terbium, Lutetium, Samarium, and Yttrium must apply for an export license from the China Ministry of Economy. The application requires customers to detail the final use of the material.
https://en.wikipedia.org/wiki/Mountain_Pass_Rare_Earth_Mine
The Mountain Pass Rare Earth Mine and Processing Facility, owned by MP Materials, is an open-pit mine of rare-earth elements on the south flank of the Clark Mountain Range in California, 53 miles (85 km) southwest of Las Vegas, Nevada. In 2020 the mine supplied 15.8% of the world’s rare-earth production. It is the only rare-earth mining and processing facility in the United States.[1][2] It is the largest single known deposit of such minerals.[3]
As of 2022, work was ongoing to restore processing capabilities for domestic light rare-earth elements (LREEs) and work has been funded by the United States Department of Defense to restore processing capabilities for heavy rare-earth metals (HREEs) to alleviate supply chain risk. [4] The mine was reported as operating in 2025.[5]
After China’s 2010 rare earth elements embargo, the United States, the European Union, and Japan filed a case against China at the World Trade Organization, ultimately forcing Beijing to remove export quotas by 2015. The United States also revived rare earth mineral processing, including efforts to reopen the Mountain Pass Rare Earth Mine in California. In 2023, Washington intensified its “friendshoring” strategy by allocating additional resources to domestic mining and refining through the Department of Defense and Department of Energy budgets, while also strengthening supply chain partnerships with allies like Canada and Australia.
U.S. efforts to reduce dependence on China for critical minerals face a number of significant hurdles. First, domestic refining expansion remains slow, with new processing plants and smelters taking 10–20 years to become operational. For example, the Mountain Pass Rare Earth Mine, which reopened after China’s 2010 export controls, still sent 98 percent of its raw materials to China in 2019 due to the lack of U.S. processing capacity.

With our re-commissioned processing facilities, we now deliver separated and refined products, including high-purity NdPr oxide, the cornerstone of the world’s strongest and most efficient permanent magnets.
I don’t know what portion of processing you’re capable of doing for what materials, but I sure hope that you guys have found a way to fill that processing capacity gap and reliance at some point between 2019 and now.
EDIT: Though Russia’s been obtaining US components via shell companies in China using false pretenses, and I suppose that that’s a sword that cuts two ways, unless China intends on also cutting off the rest of the world. We’ve played the “shell company in other countries” game ourselves, and I imagine could do so again if need be.
https://en.wikipedia.org/wiki/Lockheed_SR-71_Blackbird
The Lockheed SR-71 “Blackbird” is a retired long-range, high-altitude, Mach 3+ strategic reconnaissance aircraft developed and manufactured by the American aerospace company Lockheed Corporation.[N 1] Its nicknames include “Blackbird” and “Habu”.[1]
The SR-71 was developed in the 1960s as a black project by Lockheed’s Skunk Works division.
Titanium was used for 85% of the structure, with much of the rest being polymer composite materials.

The more significant problem, however, was that the United States simply did not have sufficient reserves of domestic titanium ore to construct planes from. The Soviet Union, however, did and had made it available for export.
Of course, if the Soviet Union had known that its exports were being used to build American planes, then it certainly would not have sold them. And even if the United States had not declared the purpose of its imports, bureaucrats in Moscow would likely have raised their eyebrows at the quantities of titanium that the U.S. government was suddenly interested in. This led the Central Intelligence Agency to begin a program of clandestinely buying the ore, using dummy corporations and third world countries as intermediaries.
Ultimately, the CIA was able to secure enough titanium to construct 32 SR-71s, along with more than a dozen A-12s and a handful of derivative planes—all from minerals illicitly obtained from the Soviet Union.
Good. Stop mining this and leave it alone.
Are you willing to give up all the products that need these? And all the services you consume that use these?
Yes. We obviously aren’t responsible enough to handle these devices as it is now. We are eroding our planet of its life by causing drastic changes to our climate, caused by burning up massive amounts of fossil fuels to power our “AI”. This is gross and detestable, and we should reverse course immediately until we can find better alternatives to handle semiconductor manufacturing processes, and find better ways to power these devices. Not stopping now will only add more Co2 emissions to our planet’s atmosphere, which will increase global temperatures.
What you’re suggesting is “pennywise and pound foolish” if your goal is CO2 reduction. Semiconductors and Rare Earth metals are required for our best weapons against CO2 emissions, those being wind turbines and PV solar panels.

Energy demands are far FAR larger than the minuscule (by comparison to other energy users) AI data center waste.

Fossil fuel lovers will back you 100% on reduction of semiconductors as it means a lock-in for electricity generation to mostly fossil fuels.
Yes.
So no modern electronics or computers then? So back to maybe basic transistors at best? You’re cool with that?
TIL a steady transfer of rare earth metals from China is necessary for all of the computers of today to continue working. Is it like a subscription. Rare earth pass, subscribe now.
Otherwise, ya, hermit life FTW
Otherwise, ya, hermit life FTW
It won’t be hermitage for us, it will likely be death from starvation and disease. Global supply chains, including those for food production and distribution required modern technology. If you’re going back to pre-computer world you have to roll the clock back for how much of a population the world was able to support. The first transistor was made in 1947, which is arguably the beginning of modern electronics (a few vacuum tube computers existed before this time).
World population a few years later in 1951 was 2,536,927,035. The world population today is 8,231,613,070. So your suggested change will kill off about 5,694,686,035. Even Marvel’s Thanos was only trying to kill off half of the population, and here you are suggesting Thanos wasn’t going far enough where you want about 70% of everyone dead.
To think either one of use would survive is hubris.
Nice MO (besides the voting manipulation)
Oh no, that argument about current capabilities ruins my whole schtick, let me pick up a PS so I can counter argue a red herring…
You must be from the US
edit: more than half of the people in the world live in Africa/Asia, I don’t see those regions being particularly affected by rare earth metal restrictions. Microsoft, OpenAI and Apple et al might be fucked though, and that means that scenario would be a good thing.
You don’t think nations in Africa or Asia use computers, electronics, telecommunications equipment, medical device for things like imaging or chemical analysis in their logistics or supply chains?
Ahh! I understand now! You didn’t read the thread you’re responding to where the OP said these metals shouldn’t be mined at all. You just jumped in and provided an answer for a question you didn’t understand, then you attack my response because of YOUR misunderstanding. You think you’re responding to a tariff question, and not the OPs position of climate change.
Please try to read what you’re replying to next time before you make yourself look foolish like this again.
