China‘s Iron Grip on the Rare Earth Magnet

  • 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.

      "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.

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.

      Those guys are masters in rebuilding, but they do it in kinda backyard shops sitting in squad in the dust where they solder the lead without any respiration filter and pour the rinsing solution for cleaning somewhere, I assume in the landscape.

    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.

      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....

    My math tells me that with cheap enough energy you can desalinate seawater and extract all the rare earths, gold, even uranium from the waste salt stream. It looks like the most efficient way to do this is with ion bind and release resins. The fresh water would support agriculture and household use. I think you need next generation nuclear and solar to come up with the cheap power.

    Or the competition between China and the United States has broken the benefits of globalization, and the United States is afraid that China, which is different from him, will gain the advantages he once had in all aspects, at least do something when he still has advantages, such as technology export restrictions, or Included in the review list to restrict imports. China, even if its target is not the United States, has to respond, including the same export restrictions, and localization of technology as much as possible.

    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.

    Big advantage of the ferrite magnets is that they are, to a large extent, also a ceramic, and thus an insulator, thus lower eddy current losses in use, and thus lower loss in the magnet due to induced current.
