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.
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.
Neodymium and dysprosium are two rare earth elements REEs, out of a group of 17 elements. Due to their unique properties, REEs gained increasing importance in many new technologies, like wind turbines, batteries, etc. However, the production of REEs requires high material and energy consumption and is associated with considerable environmental burdens.

Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.

This document provides a description of the many environmental facets of the rare earth mining and disposal issues, and explains the need for a national strategy for the continued supply of required REEs in future technological development nationally and internationally, and for the reuse of these materials versus disposal in landfills.
Oct 27, 2019 An insatiable demand for the copper, lithium and rare-earth metals required to fuel the consumer electronics and electric vehicle industries is leaving indelible scars on our fragile planet
Jan 17, 2018 Rare metals are especially vital for renewable energy technologies, such as electric cars and solar panels. For example, a single Tesla vehicle requires about 15 pounds, or a bowling balls worth, of lithium, and thin, cheap solar panels need tellurium, one of the rarest elements on Earth.
The review paper mainly focuses to provide scientific literature about rare earth elements REEs with potential environmental and health effects in understanding the research. This is the initial review of RE speciation and bioavailability with current initiative toward development needs and research perceptive.
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 may result in serious environmental
Dec 07, 2016 Mining and processing of heavy and rare Earth minerals can produce a tremendously negative impact on the land and environment in the area, the magnitude and intensity of which depends on the kind of chemicals and processes used, the efforts taken in the management of waste as well as on environmental fragility of the location.
protocols could be an important positive step for the mining industry. LCAs are complementary to other traditional evaluations, such as environmental impact assessments EIA, which explore other forms of impacts, such as those on biodiversity. Early-stage assessment could help cut production impacts of rare earth elements continued
It can be seen that mining enterprises should improve the conversion and application of science and technology in the mining, smelting, and separation of rare-earths, reduce the cost of expenditures, and reduce the loss of the ecological environment by the rare-earth industry.

Aug 25, 2016 Rare earth metals, hard-to-find materials, with unfamiliar names such as lanthanum, neodymium and europium, are used in wind and solar energy projects, but dwindling supplies could hinder a roll-out of low carbon technologies and slow Chinas shift away from coal power. These compounds, which are highly toxic when mined and processed, also take a heavy environmental toll
Feb 15, 2013 The study, done by a Germany company in January of 2011, is entitled Study on Rare Earths and Their Recycling ..

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
