Rare-earth mining is a complex activity, with extraction that has a major impact on the environment (as it is carried out in open-pit mines) and processing that generates a large amount of toxic waste (since the different minerals have to be washed with acids to separate them).
Market pressures for cheap rare earths may lead managers to skimp on environmental protections. Contrary to their name, the 17 rare earth elements are relatively common — their rarity comes from the …
Credit: Getty. China is threatening an export ban on rare earth metals in response to Washington's recent decision to impose restrictions on exports of high-end semiconductors to Beijing. This is not the first time that China has mooted such a ban, with rumours circulating since at least 2019 as well as formal threats in 2021.

Globally, China controls most of the market for processing and refining for cobalt, lithium, rare earths and other critical minerals. Executive Order 14017 (E.O.), America's Supply Chains,...
This cannot end up costing the Earth. China established its dominance over the rare earths industry because of lax environmental regulations and a cheap workforce. It has paid a high price....
Most worrying is that rare earth ores are often laced with radioactive thorium and uranium, which result in especially detrimental health effects. Overall, for every ton of rare earth, 2,000 tons of toxic …
The elements range in crustal abundance from cerium, the 25th most abundant element of the 78 common elements in the Earth's crust at 60 parts per million, to thulium and lutetium, the least abundant rare-earth elements at about 0.5 part per million.
1 day agoIonic Rare Earths (IXR) kicks off process commissioning for its magnet recycling demonstration plant facility in Belfast, UK; The company remains on track for the first production of separated and refined high-purity magnet rare earth oxides from the demonstration plant by late June
The rare earth elements were impurities that prevented a nuclear chain reaction by absorbing neutrons. The rare earths needed to be separated and removed in the process of purifying uranium. Out of Spedding's …
Ever since the increasing importance of rare earth elements (REEs) for green technologies, such as wind turbines, electric vehicles, and low-energy lighting, there has been a parallel discussion concerning environmental impacts caused by the mining and production of REEs.
China only has around 36 percent of the world's known rare earth reserves, but through a deliberate and methodical strategy, Beijing now controls more than 70 percent of the world's extraction...
When rare earth prices rose in 2010 and 2011, mines outside of China began to ramp up, including Molycorp's mine in Mountain Pass, California, which had …
China's dominance over the supply of rare earths — which are critical for energy transition and defense technologies — should spur U.S. policymakers to bolster raw materials supply chains, write energy fellow Michelle Michot Foss and co-author Jacob Koelsch. ... We note that the issue of cost to "reshore" or "friend-shore ...
Lanthanides are rare earth elements (REEs) which are often used in electronic devices like computers, mobile phones, and green technologies like catalytic converters and electric car batteries. Its d emand is expected to grow exponentially, and its market is projected to reach US $9.6 billion by 2026. Given its profitability, d eveloping …
Merely having deposits of rare earths is no guarantee of being able to exploit them. The mining and extraction processes are capital-intensive, consume large amounts of energy, and release...

9/8/2021. By Stew Magnuson. A rare earth mine in Baiyunebo mining district of Baotou in north China's Inner Mongolia Autonomous Region. AP photo. This is part 2 of a 3-part special report on the rare earth market. In 1987, then-Chinese President Deng Xiaoping famously said, "The Middle East has oil. China has rare earths.".
Rare earths are mined by digging vast open pits in the ground, which can contaminate the environment and disrupt ecosystems. When poorly regulated, mining can produce wastewater ponds filled...
