Loss of Permanent Magnet Magnetization Due to Cold Temperatures Exposure

Loss of Permanent Magnet Magnetization Due to Cold Temperatures Exposure Loss of magnetization due to cold temperatures exposure is a phenomenon that occurs in various types of materials, particularly in magnetic materials. This phenomenon is commonly known as the “superparamagnetic effect” or “temperature-dependent magnetization.” It results from the thermal agitation of the atomic spins in the…

Rare Earth Mining by GMDC

What is Rare Earth?

Rare Earth refers to a group of 17 naturally occurring metallic elements with unique properties and a wide range of industrial applications. These elements are essential for the global transition to a low-carbon economy, particularly in the production of clean energy technologies. Their critical role in the advancement of technology and sustainable development underscores the importance of securing a stable supply of these elements. REEs are divided into two categories:

Light Rare Earth Elements include elements like lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd) and samarium (Sm). These elements are abundant and generally have a low atomic weight. 

Heavy Rare Earth Elements include elements such terbium (Tb), dysprosium (Dy) and yttrium (Y). They are less abundant and have a higher atomic weight. 

GMDC’s Portfolio includes High Purity Light Rare Earth Oxides 

Neodymium (Nd) and Praseodymium (Pr) are essential for making the strongest permanent magnets which are critical for motors in EVs and wind turbines. 

Lanthanum (La) is primarily used in the catalytic cracking process in the petroleum industry, as well as in  the electronics, optics industries and batteries for hybrid cars. 

Cerium (Ce) is used in catalytic converters in the automotive industry, as polishing powder for glass products and in electrical components. 

Developing India’s Sustainable Permanent Magnet Supply Chain 

We aim to develop an end-to-end REE value chain from rare earth mining, processing, separation and end-product manufacturing. We are establishing one of the world's top rare earth processing hubs in India. The hub will integrate the entire REE value chain and support downstream activities across industries such as metals or alloys, NdFeB magnets, electric motors, glass and optical glass manufacturing in India. 

Mining and Beautification in Ambadungar 

GMDC is developing one of the world’s largest rare earth deposits at Ambadungar, a village in Chhota Udepur district of Gujarat. The project includes an open pit mine, processing plants, tailings storage facility, water supply, bulk power supply, mine infrastructure, workshops, offices, modern residential facilities with a best-in-class living ecosystem. 

Our Ambadungar deposits contain light earth elements (LREEs), which are critical minerals for most economies globally. The ore will be mined from an open-pit mine and transferred for processing through crushing, milling, conditioning and floatation to form a mixed rare earth concentrate. 

Separation and Integrated Downstream Manufacturing at Bharuch 

The mixed rare earth carbonate produced in Ambadungar will be transferred to our separation plant in our REE hub at Bharuch. The end-result from this separation process will be the valuable rare earth oxides - Nd, Pr, La, Ce. 

These separated oxides will be converted into metals and further used in manufacturing products such as catalysts for catalytic cracking as well as rare earth magnets - which are essential for the global transition to clean energy and mobility. GMDC provides critical minerals from rare earth mining.

A new way to control the magnetic properties of rare earth elements

The special properties of rare earth magnetic materials are due to the electrons in the 4f shell. Until now, the magnetic properties of 4f electrons were considered almost impossible to control. Now, a team from HZB, Freie Universität Berlin and other institutions has shown for the first time that laser pulses can influence 4f electrons- and thus change their magnetic properties. The discovery, which was made through experiments at EuXFEL and FLASH, opens up a new way to data storage with rare earth elements. The strongest magnets we know of are based on rare earths. Their 4f electrons are responsible for their magnetic properties: They generate a large magnetic moment that is maintained even when their chemical environment changes. This means that rare earths can be used in very different compounds and alloys without changing their special magnetic properties.

Realizing I can embed magnets in the EVA foam so my headcrab mask can wear teeny tiny silly littol hats if I attach magnets to them, too

AH I REMEMBERED WHAT I WAS GONNA SAY EARLIER but it's kind of stupid, lmao.

So my partner is getting into brewing beer and I got them a Tilt, which is a Bluetooth hydrometer. It measures specific gravity and temperature, which are things you want to know so that you don't kill your yeast or whatever. Except the sensor's Bluetooth range is super short, and it basically runs via a phone app, and the temperature we're logging currently is the crawlspace, accessible via the staircase closet. So they were like, wait, what do we do about this, because I can't leave my phone in the closet, that's my alarm clock.

In a kind of ridiculous turn of life imitating art, I was like, hold up, I got just the thing right at my desk. Bam. Old phone. We just needed to scrounge up a charger because the battery is so dead that after charging just enough to power on it claimed it was at 53% (to be fair to it, there is a very real chance that it's correct, and it just holds no charge at this point so the capacity is just THAT low) and now it lives in the closet logging sensor data.

And I was like, you know...didn't I just solve a major story detail with a much larger version of this...yeah, no, this is all vaguely familiar somehow, power supply issues and all. Kind of cool that the concept works though. Kind of weird that it came up at all?

We are not gonna talk about the fact that I still have at least two more ancient-ass phones in a drawer where that came from because look, man, sometimes you just need a camera/mic/mini computer with Bluetooth and wifi that fits in a pocket, and people just get rid of these things, but not me. I actually could build a shitty security system out of them if I was reaaaally inclined. I mean. I'm not. But it's technically possible.

For real though, If I pick up any stupid maker projects I still high-key am thinking about slapping Bluetooth into a necomimi headset and running that through an Arduino and learning to code just enough to let me skip songs/change the volume on Spotify with my brain, because it's entirely doable, and I mean yeah I could do that on my phone remotely too, but that's not funny, now, is it. I'm just not sure it's $350+ of parts funny. Kind of a big investment just to prove the point that haha look I am the extremely ADHD type of lazy where I would rather solve a problem via the most convoluted and complicated Rube-Goldberg type ass machine way possible rather than just perform a single simple action.

YEAH I'VE BEEN THIS SCATTERED ALL DAY AND I REALLY SHOULD GO TO BED SHOULDN'T I. I started playing Satisfactory. Mistakes were made. I'm going to dream about conveyor belts again and I did it to myself...

[awesome-casuallyfamouscollector]

The real reason why this news is important is that rare earth materials are critical to making the permanent magnets that are an essential component of the electric motors that the transition to an emissions free economy depends upon.

The sticking point is that China, with it predilection for dominating so many of the manufacturing processes for making electric vehicles, solar panels, and other critical technologies needed to address an overheating planet, controls over 80% of the world market for rare earth elements.

We know the danger of allowing tyrants in Saudi Arabia and Russia to control our access to fossil fuels. That experience suggests letting China be the gatekeeper for the new technologies we need to transfer away from relying on fossil fuels may be similarly fraught with danger in the future(..)

P.S. A very interesting discovery! It can be very useful to get rid of China's monopoly…

Loss of Permanent Magnet Magnetization Caused by Heat Exposure

Loss of Permanent Magnet Magnetization Caused by Heat Exposure Loss of Magnetization Caused by Heat Exposure – Exposing a magnet to high temperatures can decrease its strength or permanently damage its structure. Usually this happens at very high temperatures, but for certain neodymium magnets this can happen as low as 60°C. Magnets are characterized by two temperature thresholds: the working…
