Why this Chinese rare earths company could be caught out in the US
Rare earth elements (REEs) are important raw materials for green technologies. However, REE mining and production uses techniques that are often not environmentally sustainable. Life cycle assessment (LCA) is a well-recognized method for evaluating the environmental impacts of products and technologies. This article provides an overview of the environmental impacts based on published LCA.
America's Only Rare Earth Mine Is Stuck in a Distressed Debt Dispute
China could easily decide to restrict access to rare earths again with disastrous consequences. As of today, China accounts for 63 percent of the world's rare earth mining, 85 percent of rare.
Mining Rare Earth Elements. The Environment, Tech, And The… by ETEKLY
The "excessive rare earth mining," the council wrote, led to landslides and clogged rivers. Faced with these mounting environmental disasters, as well as fears that it was depleting its rare.
California Challenges China In Rare Earths Mining NPR
Mountain Pass mine in California is the only active rare earth mining and processing facility in the U.S. Photo: Tmy350 To limit the global temperature increase to 1.5 degrees C or close to it, all countries must decarbonize—cut fossil fuel use, transition to zero-carbon renewable energy sources, and electrify as many sectors as possible. It will require huge numbers of wind turbines, solar.
China Wrestles with the Toxic Aftermath of Rare Earth Mining Yale E360
Rare earths are also driving the growth of green technologies, such as wind energy and electric vehicles, and may even give rise to new components for quantum computers. "The list just goes on.
Are Rare Earths the Next Pawn in the USChina Trade War? WIRED
Canada's first step into mining rare earths. The Nechalacho rare earth elements mine is the first of its kind in Canada. According to Lavoie, environmental impacts were front of mind for that.
Why rareearth mining in the West is a bust — High Country News
The rare earth deposit in the North T Zone has a radius of between 150 to 200 metres, according to the project's chief geologist, Chris Pederson. "It's not going to be spiraled down like other.
Gritty Images From China's Muddy Rare Earth Mines Business Insider
Mountain Pass Mine, California. MP Materials, which operates the largest rare earth element mines in the Western Hemisphere, had a big week. It was one of three companies on Nov. 17 to receive Defense Department grants intended to return rare earth production to the United States. The following day it was listed on the New York Stock Exchange.
US rare earths miner MP Materials takes on China dominance — Quartz
Sweden has known it has rare earths for a while. LKAB was aware of some rare-earth deposits in Sweden as far back as the 1960s as it was mining iron ore, says Laura Lauri, a field exploration.
Rare earth minerals power the world, but mining leaves local and global
The rare earth concentrate is baked (or "cracked") in a hot kiln, then leached with water to remove impurities.. Merely mining and processing more rare earths will not reduce reliance on.
China's rare earth mining in Myanmar fuels rights abuses, pollution
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.

Obtaining rare earth elements begins with obtaining source materials, which can happen, broadly, in three ways: primary extraction, or mining directly from the earth; recovery from secondary.
A proChina online influence campaign is targeting the rareearths
The rare-earth industry can be divided into three stages: upstream, or the mining of elements; midstream, the processing of elements into separate oxides; and downstream, the manufacturing of permanent magnets and other components made with rare earths. Making rare earths globally available starts in the upstream stage.
The Strange Second Life Of America's Only Rare Earth Mine Gizmodo
The rare-earth mining and smelting process can release airborne fluoride which will associate with total suspended particles (TSP) to form aerosols that can enter human respiratory systems and cause damage and respiratory diseases. Research from Baotou, China shows that the fluoride concentration in the air near REE mines is higher than the.
New Technologies to Extract, Purify Critical Rare Earth Metals a ‘Game
Rare earth elements are also used in other ways that don't involve magnets. Vehicle-mounted laser range finders, such as those found on Abrams M1A1/2 tanks, make use of rare earth elements, as do.
News Revival of RareEarth Mining in the U.S.
Heavy rare earth elements (HREEs) such as Gd-Lu, Sc and Y are irreplaceable metals for a number of critical (including clean) technologies, but they are scarce. Ion-adsorption deposits, which.
