China‘s Iron Grip on the Rare Earth Magnet

Рет қаралды 185,759

Жыл бұрын

Recently, the People's Republic of China banned the export of rare earth magnet production technologies for national security interest.
Note, not the particular rare earth magnets themselves. The technologies that produce them.
There are 18 rare earth elements - the 15 lanthanides as well as yttrium, scandium, and lutetium. They have wide technological and commercial uses.
Most of these use cases are small - the OEC values global rare-earth metal compound trade volume in 2021 at about $2.7 billion - but they are vital. Thus why we call them the "vitamins" of the tech economy.
But one use case in particular stands out to me over all the others: Magnets.
And China's tech export actions hint at their strategic importance.
In just a few years, China won a near-complete monopoly on the production of these unexpectedly critical magnet materials.
And alternatives cannot economically compete. In this video, let us take a look at the special economic power of the rare earth magnets.

I think an important part of the story which wasn't included is that when rare earths are always found in association with quite high concentration of thorium. When the ore is cracked the thorium is released concentrating radioactive waste material. Western countries moved away from this process but China continued. This problem presents when western countries off shore the process - there was real problems when Lynas corp moved this process to Malaysia on the early 2000s with environmental protest groups. Thus there have been multiple disincentives to mining and refining rare earths outside of China beyond scale and tech.

Yes, we have problems of radioactive discharge from the Japanese owned factory called Asian Rare Earth, located in Ipoh, West Malaysia. Due to protest and many health issues among workers and surrounding neighbourhood, this plant was forced to stop sometime in the 1990s. The problem now is dealing with the wastes which are toxic n radioactive. The storage nearby in the jungles were found to leach and it is a concern now as it may seeps into the river. Unfortunately, our Malaysian government never learnt from this predicament. It went on to grant a license to Lynas of Australia to set up a huge plant in Kuantan, Pahang state, East Coast of West Malaysia some 15years ago. Even Lynas was rejected by the Australian government to operate in Australia. Looks like Malaysia is the dumping ground for foreign hazardous materials.

Yes, the US reopened the Mountain Pass mine to reduce the national security concerns of having to rely on China for rare earth materials. We now dig up the ore and ship it to China for refining. We do this because environmental laws don't allow refining to be done in the US economically. The solution is to have China do the refining while complaining about their lack of concern for the environment and state control of the worldwide supply. Somehow this is the same government in charge of the only superpower in the world.

Seems like it's a particularly difficult refining process. "The processes that are used right now … can be 100 steps,” Chrisey said, also noting that the procedure can be very expensive and environmentally hazardous due to the chemicals used to separate and purify the metals.-- And soon, MP Materials will no longer have to ship this mixture overseas to China for the lengthy process of separating and refining the rare earth elements. After two years of construction, the company announced in November that it is on the cusp of opening the first rare earth refinement facility within the United States at the Mountain Pass facility."

Well the mining of old dumps for gold, and the profitable extraction of copper, silver and sulphuric acid from the dumps, was also a SA thing, and the end result was also that large chunks of land, all now more or less in the middle of the gold reefs, was available, plus the residue from the recovery was pumped back into the pits, both filling in the old adits, and making the ground less prone to sinkholes forming, and also keeping the local water tables free of pollution. I remember all those mine dumps being there, but now almost all are gone, replaced by housing tracts. The actual god recovery was also, because of new methods over the old mercury extraction and flotation used, actually higher than the current virgin ore being mined, despite it being already processed, and the dumps were also easier to handle, seeing as the ore was already crushed and easy to handle. Of course, you also had a good amount of both mercury and other stuff recovered, as the mine dumps were used as a catch all dumping ground by the mines.

The term "rare earth" is an old 18th century chemistry term. Almost alchemical in nature, and it causes lots of confusion, though it's very simple to understand. "Earths" were things like beach sand and quartz, silicon dioxide. These elements, though extremely abundant in the earths crust, were unobtainable in metallic form. Silica, alumina, zirconia, titania, magnesia, all of these were "earths" Carbon could not reduce them to metal, like it could do so with iron, copper, or lead. A more advanced technology was needed. Elements like lanthanum, cerium, and "didymium" (neodymium-praeseodymium mixture) resembled these earths, as they too could not be reduced to metal by carbon. Rarer than literally the most abundant elements on earth, these new earths were deemed "rare earths" now we call them lanthanides, elements like lanthanum.

There is no such thing like "shipping ore to China for processing." The export processing of rare earth has long been banned in China. MP Materials launched this spin to explain their single customer single destination in China concept, while actually none of the ore they ship to China ever comes back to MP Materials as finished rare earth products. MP Materials were substantially financed by their major shareholder, a China state-controlled entity, when buying and restarting Mountain Pass. That entity holds not only just below 10% of the shares, it also holds a warrant that brings the total stake-holding closer to 20% of MP Materials.

We actually have very few "sources" of electrical energy, real sources. Magnets and solar panels when you think of it are the only things capable of producing electricity or useable current. Batteries need to be charged, so they don't count. All motion based generators need energy feed from the exciter. This may come from many sources, but only a magnet or solar panel can provide with without relaying on something else. Even wind and water power need a magnet or another electrical power source that comes from ....you guess it a magnet as the exciter. Even nuclear power doesn't make electricity without existing power to feed the systems and the exciter found on the turbines. Once the grid is up , you can take feed from anyone else, try starting the grid from zero is not so easy.

I'm guessing the etymology is Greek from "Ceres" (mother of Persephone). The Greek letter often transliterated into the Latin "C" is always pronounced similarly to a hard "K" (never a soft "C" = "S"). This means a lot of common English pronunciations of Greek origin words are technically incorrect. Cenotaph, centaur, cyan, ceramic - among many others - are most correctly pronounced with a "K" phoneme at the start, rather than an "S". Pointing this out can get you labelled a pedant and obscurantist however....

The material itself isnt too rare, But whats rare is the processing the materials Which patents are mostly owner by China 😂

I think it's justified to country that hold rare Earth material to monopolized it, consider they're the only one that gonna get impact of mining operation,so more economic power more ability to recover the environment that damaged

Videos like these illustrate just how much the US China economic partnership benefits America. The US gets affordable consumer goods, access to unavailable or infeasible natural resources as well as access to a burgeoning consumer market for American goods like the iPhone, Tesla cars and agricultural produce.

I noticed several keyboard warriors correcting you about the sodium hydroxide. Good. Having said that, I find the idea that recycling rare earth magnets is not economically viable to be insane. Using a source that is already a rare earth magnet and turning that into a new rare earth magnet has to be a lot easier than complicated, expensive, ecologically damaging methods required to refine rare earths at concentrations of less than 50 parts per million. The only slightly challenging part of recycling rare-earth materials from e-waste is the collection and separation of materials. It just doesn't seem to be a difficult problem.

I agree. I think the general problem with most recycling, however, is economically sorting and isolating waste streams to get all of those magnets out of the products they’re used in. Imagine a recycling regime where high-performance headphones are collected and the magnets are removed for collection and then processing. Even if the collection process is perfect, how are you going to get most people to go out of their way to set their headphones apart or sort them out of the broader waste-collection system? Even if everyone does that willingly, those then have to all be disassembled - which I guess could just be crushing and passing an electromagnet over in this case - are we sure that can be done economically? I’m not trying to shut you down or be particularly negative. I just believe these are the key difficulties that any sufficient recycling effort must sufficiently address.

@@tictacdude3468 Yes, you have a point about getting the valuable material seperated from the dross, but that is the process of recycling. Most people already separate their e-waste from their other types of waste. That's more than half the work done already. I smell a huge opportunity here.
