Rare earths are used in the renewable energy technologies such as wind turbines, batteries, catalysts and electric cars. Current mining, processing and sustainability aspects have been described in this paper. Rare earth availability is undergoing a temporary decline due mainly to quotas being imposed by the Chinese government on export and action taken against illegal mining operations.
Expansion of mining operations and changes to milling and processing operations may require environmental review and additional permitting for these active mining operations. In addition to rare earth production from current mining sites, it could become .

Case studies like these illustrate the result of ignoring the environmental damages of mining, and leaving them unaddressed or unregulated. ... and sulfuric acid for each ton of rare earth elements produced. Additionally, nearly 75 cubic meters of acidic waste water and one ton of radioactive waste residue are generated (Paul Campbell, 2011 ...
The Mountain Pass Rare Earth Mine is an openpit mine of rareearth elements on the south flank of the Clark Mountain Range, just north of the unincorporated community of Mountain Pass, California, United mine once supplied most of the world''s rareearth elements. Owned by MP Materials, it is the only rare earth mining and processing facility in the United States.
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 ...
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.
There are multiple examples of negative past experiences and incident associated with RE processing—for example, the Asian Rare Earth Company in Malaysia (1982–1992) (Golev et al., 2014). On the other hand, ceasing REM production because of severe negative environmental impacts threatens the RE supplydemand balance.
It''s a sight hard to associate with the environmental technologies that rare earths are used in. Water in and around the mining area is severely polluted. According to China Environmental News, the water supply for 30,000 people in the county of Longnan alone has been affected by rare earth mining, ...
Over the past decade, China has supplied over 90% of global rare earths, and in doing so bore significant environmental burdens from processing its complex ores. In this study, we used life cycle assessment to quantify environmental impacts for producing 1 kilogram (kg) of 15 rare earth elements from each major production pathway.
