Dec 08, 2015· 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. REEs have not been mined in the United States for about 20 years, and prior to that time, the …
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.
Apr 05, 2019· Environmental hazards due to rare earth mining. The dangers of mining rare earth metals are not limited to human and animal life. There is a lot of harm caused to the environment due to the hazardous toxic waste. If the mining, recycling and refining is not done responsibly, then the environmental impact is quite serious.
Aug 12, 2021· 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.
Jan 28, 2013· 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.
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 ...
Jan 01, 2014· Social resistance to rare earths mining stems from arguments about environmental justice and how processing sites are often more difficult to get permitted in developed countries - leading to their construction in developing countries. ...
