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.


The assumption that the way that we've always mined rare earth elements is the only way that we can mine rare earth elements is, to me, a profound failure of imagination.

The "rare" in the name of this group of elements is actually somewhat misleading; the U.S. Geological Survey describes them as "relatively abundant in the Earth's crust." But extraction is ...


So mining of any natural resources always poses environmental consequences on the area where the resources are mined, but what is really challenging for rare earth elements is the refining process, because of what Oscar also mentioned, the low concentrations of rare earths.


Effects on environment. If rare earth resources are not mined and developed properly, not only does it result in economic losses for countries, but it also does great harm to global ecotopes, especially during the processes of mining, refining and recycling, which …

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.


Increasing rare earth mining outside of China has reduced China's global share of mining, down from 97.7% in 2010 to 62.9% in 2019. But mining is merely one piece of the puzzle. Ultimately, the large majority of rare earth refining, 80%, resides in China. Therefore, even rare earths mined overseas are sent to China for final processing.

Reprinted with permission from the publisher. Prior to the rise of rare earth mining in China, the United States dominated the world scene.


The environmental impacts of rare earth mining have recently caused public concern, because demand for the rare earth elements neodymium (Nd), praseodymium (pr), dysprosium (Dy), and terbium (Tb) is expected to increase strongly as a result of their use in magnets for electric cars and other emerging applications.


Harmful effects of the mining include contaminated soil and water, deforestation and negative health impacts on humans and other animals. These processes also require large amounts of energy. Our reliance on rare earth elements is not going to end any time soon, so researchers have begun to look for ways to obtain them in less environmentally ...


The use of rare earth elements in various technologies continues to grow despite some alternatives being found for particular uses. Given a history of ecological concerns about pollution from rare ...


A mining site in West Texas could offer the US a 130-year supply of 15 of the 17 rare earth elements. Japan has invested in an Australian site with significant deposits. Beyond mining, China dominates in processing, accounting for about 85% of the capacity.


REE Rare Earth Elements Metals, Minerals, Mining, Rare Earth Elements (REE) are becoming increasingly important in electronic devices used in the defense, alternative energy, and communications industries. Minable deposits of REEs are found in only a few locations.


Rare earths are a group of 17 elements: "iron grey to silvery lustrous metals" that are "typically soft, malleable, and ductile; and usually reactive", according to the US Geological Survey.


Rare earth elements are actually a group of seventeen elements, numbers 57-71 on the periodic table, that have a set of unique magnetic, electric, and optical properties (Namibia Rare Earths 2015). Contrary to popular belief, as well as their namesake, rare earth elements actually aren't all that rare.


TENORM: Rare Earths Mining Wastes. Click the image below to enlarge the periodic table and see which elements are known as rare earth elements. Rare earth elements, known as lanthanides and actinides on the periodic table, include 15 chemical elements with atomic numbers 57 through 71. Yttrium (atomic number 39) and scandium (atomic number 21 ...


The mining of rare earth metals, used in everything from smart phones to wind turbines, has long been dominated by China. But as mining of these key elements spreads to countries like Malaysia and Brazil, scientists warn of the dangers of the toxic and radioactive waste generated by the mines and processing plants.


Rare earth metals are found in an ever-increasing number of products we use every day, and there are major environmental concerns and serious health issues associated with the extractions of these metals. In an effort to educate myself, I read a number of different articles and studies until I found one that really described in detail rare earths, environmental impacts, applications of rare ...


Rare earth minerals are not rare, they are commonly found in the earth's crust. These metals are called rare because of the difficulties involved in extracting metals from the ore. The rare earth metals rarely occur in pure form. The costs involved in mining the rare earth metals is very high.

Rare earth elements (REEs) are a group of 15 chemical elements in the periodic table, specifically the lanthanides. Two other elements, scandium and yttrium, have a similar physiochemistry to the lanthanides, are commonly found in the same mineral assemblages, and are often referred to as REEs.

This year, various bipartisan legislative efforts have been advanced to incentivize the mining of rare earth metals. Rare earths are a group of 17 elements (such as Neodymium, Thulium, Yttrium, Lanthanum and Terbium), many of which are germane to producing electronic components and other industrial uses.


health effects of rare earth element mining: Any kind of mining has the potential to create negative impacts, depending on mine management and safety protocols, processing methods, and waste handling systems.


Much like gold strip mining in sub-Saharan Africa, or silver mining in the heyday of Argentine exploitation, the Chinese market for rare earth metals is causing the same destructive damage to the planet as its predecessors. Unsustainable exploration remains rampant in Chinese mining communities, with profit and progress before environmental concerns are the call of the day.
