A rare earth magnet, to be precise. Nowadays, most rare earth magnets are made of neodymium, but there still may be some from the '70s kicking around which were made of a samarium-cobalt alloy . The magnets are fairly cheap and you can pick one up on Amazon for under $20 (you can get them at Home Depot, Lowe's, and even Michael's too, but ...

REE were bioleached effectively from phosphor powders and cracking catalyst. Abstract Microbial cultures were evaluated for organic acid production and their potential utility for leaching of rare earth elements (REE) from retorted phosphor powder (RPP) and spent fluid catalytic cracking (FCC) catalyst.

The monazite concentrate 1 was then mixed (in ~50 g batches) with concentrated sulphuric acid (H 2 SO 4) and heated to ~220°C in a stirred pot over a ~3-hour period to convert the contained REEs into soluble rare earth sulphates (i.e., the 'sulphation crack'), which were then dissolved in a water leach to bring the REEs into solution (i.e ...

Rare earth elements need to be extracted as efficiently and sustainably as possible because they are key components in countless technological applications, such as medical contrast agents, lasers, guidance systems, smart phones and petroleum cracking catalysts. For all of these applications, rare earth elements are needed in a near purified form.

Rare earth elements play an important role in petroleum refining, but the sector's vulnerability to rare earth supply disruptions is limited. Lanthanum is used in fluid catalytic cracking (FCC), an important part of petroleum refining. However lanthanum supplies are less critical than some other rare earths and

A bioleaching process to extract rare earth elements (REE) from fluidized catalytic cracking (FCC) catalysts was optimized using a heterotrophic bacterium Gluconobacter oxydans to produce organic acids from glucose. Parameters optimized included agitation intensity, oxygen levels, glucose concentrations and nutrient additions.

Cracking is the critical issue of "hard-to-weld" nickel-based superalloys, especially in the component fabricated by selective laser melting (SLM). In the work, the cracks of as-printed René 104 superalloy were successfully eliminated by microalloying with Sc.

As Lutetium is rare and difficult to extract, this rare earth metal is mostly used in research. It has limited commercial use as a catalyst to crack hydrocarbons in oil refineries and certain types of radioactive particle detectors. What Makes Lutetium So Valuable

Neodymium magnets are brittle and will peel, chip, crack or shatter if allowed to slam together, even from just a few inches apart. Despite being made of metal and coated with a shiny nickel-plating, they are not as hard as steel. Shattering magnets can send small sharp metal pieces into the air at great speeds. Eye protection is recommended.

USA Rare Earth has announced it will process rare earths onsite and projects the mine is likely to yield 16 or 17 rare earth elements and more than 300,000 metric tons of rare earth oxides. Currently, the only U.S. rare earths mining and processing facility is the Mountain Pass mine in California's Mojave Desert.

The city of Kalgoorlie, Western Australia, has been selected as the location for the new cracking and leaching plant to be operated by rare earth industry giant Lynas Corporation Limited (Lynas).

Rare earths, such as lanthanum, are used in crack- ing catalysts to refine crude oil into gasoline, distillates, lighter oil products and other fuels. They are also respon- sible for eliminating leaded gasoline. The use of these lanthanide fluidized cracking catalysts also promotes very energy efficient petroleum cracking.

Government scientists and university researchers are racing to find a way to extract rare earth elements from coal waste, an effort that is now also drawing the interest of the congressional coal caucus. If the scientists can crack the code, the technology ...

The rare earth chloride recovered from monazite may become a new growth engine for rare earth ore supply. China rare earth exports landscape. China's rare earth exports are mainly NdFeB permanent magnets, followed by oxides and metals of non-permanent magnet elements such as lanthanum, cerium and yttrium. The exports of rare earth permanent ...

Lutetium is also counted among rare earth metals. But unlike lanthanum, lutetium has very few commercial uses. However, stable lutetium can be used as catalysts in petroleum cracking in refineries and can also be used in alkylation, hydrogenation, and polymerization applications.
