1 In 2018 China produced some 120,000 metric tons of rare earths, while the U.S. produced 15,000 metric tons, according to the U.S. Geological Survey. Mountain Pass was once the top global supplier of rare earth minerals, but China began taking over the market in the 1990s as demand surged with the emergence of new technologies like smart phones.

Rare-earth magnet ingestions have a different age distribution than traditional magnets and foreign bodies in general. A recent retrospective analysis of data collected by or reported to the US Consumer Product Safety Commission (CPSC) identified 72 cases of rare-earth magnet ingestion–related injuries among children 15 years or younger.

Rare Earth Elements from Coal. Coal and coal preparation products are also potential sources of rare-earth elements. REEs are a group of elements (shown in purple on the periodic table below) unknown to most people. They include the lanthanide series elements (cerium through lutetium), yttrium, and scandium. Although relatively unheard of, rare ...

MP Materials helps fuel the electrification of global infrastructure. We are the largest producer of rare earth materials in the Western Hemisphere, through our state-of-the-art, zero-discharge operations in Mountain Pass, California. We currently deliver approximately 15% of global rare earth supply with a long term focus on Neodymium ...

Rare Earth Ore Classification. Classification of ores related to alkaline rocks is also controversial. Table 2 presents a relatively simple classification that follows analogous categories for deposits related to nonalkaline igneous rocks. Some of the more unusual alkaline rocks that host, or are related to, REE ores are carbonatite and phoscorite, igneous rocks composed principally of ...

"The rare earth industry is a pillar industry here in Ganzhou and we must keep it running, but there's still more to do to figure out a truly environmentally friendly method to pursue sustainable growth," Zhang Guanjun, deputy director of the public relations department of the Ganzhou Party Committee, said in an interview.

Rare earth elements (REEs) represent the group of 17 elements comprising 15 lanthanides, plus yttrium (Y) and scandium (Sc) (Table 1).Among the REEs, yttrium was discovered first in 1794 by a Finish chemist, Johan Gadolin who isolated an oxide and called it "yttria," in a mineral collected from a quarry near the village of Ytterby in Sweden.

Rare earth elements are crucial to manufacturing phones, computers and wind turbines. China currently controls 90 percent of their production, but the US is also determined to extract these precious minerals and has just reopened a rare earth elements mine in California. Our France 2 colleagues report, with FRANCE 24's James Vasina.

However, how the rare earth texture affects the k values of Mg alloys is still not clear. In the present study, the Hall–Petch relation in a typical rare-earth containing Mg-2Zn-1Gd plate, which has a texture containing two peaks of basal poles tilting approximately ± 30° from the ND was systematically studied.

Rare earth mining can be both destructive and toxic to surrounding environments. Almost all rare earth ores contain the radioactive elements thorium and uranium (Huang, Zhang, Pan, Chen, & Zheng, 2016). As a result, the extraction and processing of rare earths can be highly toxic and have a negative effect on soil, water and human health.

The rare earth elements La to Ho (57-67) plus Th and U (90 and 92) show a high degree of correlation with each other.
