Rare earths exist here in the U.S. and can be exploited, but we have hamstrung our capacity to get them. The U.S. Bureau of Mines was shut down by Congress in 1996 and its functions were either eliminated or migrated to other government agencies such as the U.S. Geologic Survey, Bureau of Land Management, and Department of Energy.

Contrastingly, overly strict environmental regulations forced all rare earth mining and processing activities in the United States to stop, while processing plants also in Malaysia were closed ...
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.

Oct 14, 2019 Unfortunately, current recycling methods are highly inefficient and can still produce large quantities of hazardous chemical waste similar to the refinement of rare earth ores. So, mining and refining rare earth ore is harmful to the environment and recycling them is vastly inefficient is there a solution In short, the answer could be ...
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.
Jan 03, 2018 Recycling rare-earth metals is attractive for technical, financial and political reasons. In late 2010, China cut off exports of rare-earth metals to Japan in response to Japans detention of a Chinese fishing trawler captain. The DOE established its Critical Materials Strategy in 2010 and its Critical Materials Institute CMI in 2013. CMI ...
Jul 15, 2013 Highlights Less than 1 of rare earths in end-of-life consumer products are being recycled. Recycling can help to ensure a supply of the most critical rare earths. Valuable waste streams are magnets, metal hydride batteries and lamp phosphors. Recycling of neodymium avoids overproduction of cerium and lanthanum. Recycling and primary mining of rare earths are
Abstract. 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.
The supply issue of rare earth elements REE has become an increasingly important issue both ... recycling of REE should be an important part of a circular economy, especially considering the large resource demands and negative environmental impact of current REE production processes. Though much research has been performed in the area, REE ...
Oct 01, 2016 Preservation of rare earth resources calls for the development of efficient recycling techniques at the pilot-plant scale. Due to the economic and environmental costs of REE mining, it is desirable to promote the recycling and reuse of rare earths, while also minimizing the dependency on
Keywords Rare earths, environmental justice, intergenerational justice, mining, recycling. 1. Introduction The multi-billion-dollar rare earth industry supplies a critical resource for contemporary societies. Rare earth elements REEs, also known as rare earth metals, are a group of 15 lanthanide metals on the periodic table plus
Rare earth elements, often referred to as rare earth minerals or rare earth metals, are critical in a number of areas of modern technology including electric vehicles, green energy generation, electronics, military, aerospace, and healthcare. If you are thinking of investing in rare earth minerals this article explains the mining process and how they are refined.
Jun 23, 2016 A company employing a unique recycling approach for hard disk drive magnets has raised 25 million to build a facility in Austin, Texas. The Austin-based Urban Mining Co. announced the completion of Series A financing to build a rare earth magnet recycling and manufacturing facility in the city. The company uses a patented magnet-to-magnet method to recycle the neodymium magnets

Keywords rare earth mining, mineralogy, recycling, life cycle assessment 1. Introduction Rare earth elements REEs include the lanthanide series of the periodic table from atomic number of 57 to 71 starting with lanthanum La to lutetium Lu and including scandium Sc and yttrium Y.
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.
Apr 17, 2021 A rare earth mineral mining site in China. Image TwitterGlobal Times. The annual demand for rare-earth metals doubled to 125,000 tonnes in 15 years, and the demand is projected to reach 315,000 tonnes in 2030, driven by increasing uptake in green technologies and advancing electronics. This is creating enormous pressure on global production.
Nov 20, 2020 Re Mining Company Determined to Restore US Rare Earth Supply Chain When the previous mine owner invested 1.7 billion USD , there were severe engineering flaws in the initial processing to reliably extract the REEs from the concentrated crushed ore and transport from the mill to the processing facility.
Jun 25, 2019 Alexis The hazards of rare earths come at four stages the mining itself, refining the ore, managing the waste, and disposing of it. First, the mining. Blasting rare earths out of the earths crust means blasting out other elements too. Elements that werent harming anyone in the ground.
