The rare-earth elements (REE), also called the rare-earth metals or rare earths, and sometimes the lanthanides or lanthanoids (although scandium and yttrium, which do not belong to this series, are usually included as rare earths), [1] are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals. Compounds containing rare ...
Focus on polymetallic mines that can produce multiple critical minerals from a single orebody and can also expand production by recycling post-consumer waste streams, such as rare earth permanent ...
According to the United Nations in 2011, [7] as the demand for rare metals will quickly exceed the consumed tonnage in 2013, [8] it is urgent and priority should be placed on recycling rare metals with a worldwide production lower than 100 000 t/year, in order to conserve natural resources and energy. [8] However, this measure will not be enough.
Rare-earth ore, shown with a United States penny for size comparison. A rare-earth mineral contains one or more rare-earth elements as major metal constituents. Rare-earth minerals are usually found in association with alkaline to peralkaline igneous complexes in pegmatites. This would be associated with alkaline magmas or with carbonatite ...
China is reportedly moving toward banning rare earth metal exports to keep high-tech advantages within the country.
E-cycle electronic waste, reclaiming rare earths and useful metals and separating toxic components so that t hey don't poison communities. Host digital city services in green data centers powered by clean energy sources , not server farms powered by coal plants.
Electronic recycling occurs primarily in order to recover valuable rare-earth metals and precious metals, which are in short supply, as well as plastics and metals. These are resold or used in new devices after purification, in effect creating a circular economy .
A magnet created by AI could transform green technology by eliminating the need for rare-earth metals, offering a sustainable and cost-effective alternative.
