As the world’s leading producer,China’s rare earth minesaccounted for nearly 70 percent of the total global production in 2023. In 2016 China’s production share was even higher—at a stark 83 percent of global production. TheU.S. rare earths production sharewas comparatively much lower, ...
Rare earth elements are a nonrenewable and important strategic resource, and China is rich in these elements. However, the substantial exploitation of these resources has caused the migration, diffusion, transformation and accumulation of pollution sources, which in turn has a profound impact on the ...
Indeed, mining companies are now actively seeking for new exploitable rare-earth deposits and old mines are being reopened (Humphries, 2012). For instance, the Mountain Pass Mine in California restarted production in 2012. However, the absence of economical and/or operational primary deposits on ...

The process towards approval of new mines is lengthy and demanding in the Nordic country, as operations often raise the risk impacting water resources and biodiversity in the areas where they are located. Additionally, Erik Jonsson, senior geologist at the Department of Minera...
China had the lowest prices for REMs which forced competing mines around the world to stop production. At the time, this ultimately led China to restrict REM exports that led to a significant rise in price for the materials. This forced the United States to figure out how to consume less ...
[04:48.64]Reg Spencer, an expert with investment bank Canaccord said the country could have two or three more mines by 2030. [05:01.51]A barrier to getting big mining projects started has been a 70 percent drop in the...
“Most rare earths mines are struggling to break even under low prices while early-stage projects face delays and funding shortfalls,” according to a Sept. 3reportin Benchmark Source. Those factors are “potentially slowing the West’s push to reduce dependence...
