Rare earth elements occur in many minerals but typically in concentrations too low to be refined in an economical manner; the concentration of REEs in the Earth's crust is estimated to be between 150 to 220 parts per million, which is higher than the concentration of other metals mined for industrial use, such as Cu or Zn.

In addition, we analyzed the supply chains of two specific defense systems to

Rare earth elements are a group of metals that are critical ingredients for a greener economy, and the location of the reserves for mining are increasingly important and valuable. ... While the United States has 1.5 million tons in reserves, it is largely dependent on imports from China for refined rare earths. Ensuring a Global Supply.

Current global REE demand is consistently estimated to be 105,000 tons (+/- 15%) of rare earth oxides (REOs, the main way REEs are purchased) per annum (Hatch, 2012; Alonso et al., 2012). The following chart shows the breakdown of total REE demand by end use and continent. Global Estimates of Demand for Total Rare Earth Oxides in 2011 (+/- 15%)

The US has long relied on China for rare earth metals, but domestic supply chains are being pursued as climate and technology investments increase under Biden.

China, Horrocks noted, has only a third of global reserves of rare earths, but in 2017 produced over 80% of the global supply of rare-earth metals and compounds, and its exports that year to the US accounted for 78% of the 17,000 tons of US rare-earth imports. Even rare-earth metals mined in the USA are processed in the People's Republic ...

Rare Earth Oxides are used in mature markets (such as catalysts, glassmaking and metallurgy), which account for 59% of the total worldwide consumption of rare earth elements, and in newer, high-growth markets (such as battery alloys, ceramics, and permanent magnets), which account for 41% of the total worldwide consumption of rare earth elements.

We report magnetic anisotropics (Δ χ) depending on rare earth (RE) element in the paramagnetic REBa 2 Cu 3 O y (RE123) system as an important finding of magneto-scientific grain-orientation. The c-axis-oriented RE123 powder samples using static or rotating magnetic fields were fabricated at room temperature to clarify Ax.

In addition to the four main types of magnets listed above, rare-earth magnets are divided in two: Light Rare Earth (LRE) and Heavy Rare Earth (HRE). "The global rare-earth reserves consist of approximately 85 percent LRE and 15 percent HRE. The latter are the ones providing magnets rated at high temperature that are suitable in many ...

Neodymium is a so-called rare earth element, a silvery metal with a very important role in renewable energy. When combined with iron and boron, it makes strong magnets that are important both for ...

Given that, the Pentagon is likely to become even more dependent in the coming years on high-tech magnets, motors, lasers, computers, and electric-drive systems that use rare-earth materials. But as noted above, the US itself no longer produces rare-earth ore or processes the substance at early points along the supply chain.

The magnetic properties of the rare-earth metals, alloys, and compounds are very dependent on the number of unpaired 4 f electrons. The metals that have no unpaired electrons (scandium, yttrium, lanthanum, lutetium, and divalent ytterbium) are weakly magnetic, like many of the other non-rare-earth metals. The rest of the lanthanides, cerium ...
