But magic comes at a cost, and in the case of mining and processing rare earths, that cost is environmental devastation. Most of us in the Western world aren't aware of the destruction because most rare earths are mined elsewhere. But some scientists are trying to find a more environmentally sound way to get them.
China dominates the mining and processing of rare earths. According to the USGS, in 2020 China produced 140,000 metric tons of REO equivalents, or 58.3 percent of the global supply. The next-largest producers were the United States (38,000 metric tons of REO), Myanmar (30,000) and …
"Establishing an independent domestic rare earth and critical minerals supply chain is monumental for USA Rare Earth and for the US, overcoming reliance on China for materials and processing that are essential for defence applications and advanced technology manufacturing," said Pini Althaus, chief executive of USA Rare Earth.
Rare earth minerals are a highly valued commodity. China currently controls 80% of the world's resources and refines most of the rare earth minerals mined in the world. This in and of itself is not an issue unless rare earth minerals become politicalized, which occasionally they do. In 2010 China restricted rare earth mineral shipments to Japan.

The principal economic sources of rare earths are the minerals bastnasite, monazite, and loparite and the lateritic ion-adsorption clays. The rare earths are a relatively abundant group of 17 elements composed of scandium, yttrium, and the lanthanides. The elements range in crustal abundance from cerium, the 25th most abundant element of the 78 common elements in the Earth's
For every ton of rare earth produced, the mining process yields 13kg of dust, 9,600-12,000 cubic meters of waste gas, 75 cubic meters of wastewater, and one ton of radioactive residue. This stems from the fact that rare earth element ores have metals that, when mixed with leaching pond chemicals, contaminate air, water, and soil.

The dangers of mining rare earth metals to human health. Rare earth metals cause harm to humans by getting inside the body through the mouth, skin and respiratory tract and via injections. It is removed from the body through the body via bile discharge and urine. Those metals which remain in the body have harmful effects.
Rare earth metals — those 17 chemically similar elements at the bottom of the periodic table — are in almost every piece of technology we use from cell phones to wind turbines to electric cars. Because these elements are so similar to each other, …
The Round Top Heavy Rare Earth, Lithium, and Critical Minerals Project in West Texas hosts a wide range of critical heavy rare earth elements (REEs) and high-tech metals (including battery grade lithium, gallium, zirconium, hafnium and beryllium). Due to the straight forward mining process and sustainably focused power generation, Round Top ...
Many rare earth elements reside among mineral deposits with radioactive materials that can leach into the water table. Mining, processing and disposal can …
rare-earth element - rare-earth element - Processing ores: All rare-earth ores contain less than 10 percent REO and must be upgraded to about 60 percent in order to be processed further. They are first ground to a powder and then separated from the other materials in the ore body by various standard processes that include magnetic and/or electrostatic separation and flotation.
SUNDANCE – Mining and processing rare earth elements is a particularly complicated endeavor. Unlike other minerals such as gold and silver, rare earth elements can't be removed from the ground
Monazite is one of the most common minerals of rare earth elements. Rare Earths Mining. Rare earths are a set of 17 chemical elements in the periodic table that, because of their unique geochemical properties, are typically widely dispersed in the Earth's crust and are not often found in concentrated and economically exploitable forms.
Rare Earth Element (REE) mining, processing and exploitation are large scale industries that use a wide range of chemical substances and generate significant quantities of waste. Additionally, the ores contain variable amounts of impurities such as non-target toxic metals, fluorine and radionuclides that may be released from the ore during ...
Rare earth processing in China is a messy, dangerous, polluting business. It uses toxic chemicals, acids, sulfates, ammonia. The workers have little or no protection. But, without rare earth ...
An Ecological Disaster In Every Circuit. The process of mining REEs is ecologically devastating. Processing one ton of rare earth metals releases 2,000 tons of radioactive materials, carcinogens, toxic compounds, acids, and other pollutants into the environment. Since thorium and uranium often occur alongside REEs in nature, tailings from mines ...
