Rare Earth Elements - Massachusetts Institute of Technology

Rare earth elements occur in many minerals but typically in concentrations too low to be refined in an economical manner; the concentration of REEs in the Earth's crust is estimated to be between 150 to 220 parts per million, which is higher than the concentration of other metals

An element that's rare on Earth is found far, far away ...

The researchers found traces of this brittle, semiconducting element — which is very rare on Earth — in stars that are nearly 12 billion years old. The finding supports the theory that tellurium, along with even heavier elements in the periodic table, likely originated from a very rare type of supernova during a rapid process of nuclear fusion.

Apr 09, 2012  The study looked at 10 so-called “rare earth metals,” a group of 17 elements that have similar properties and which — despite their name — are not particularly rare at all. All 10 elements studied have some uses in high-tech equipment, in many cases in technology

Evaluating Rare Earth Element Availability: A Case with ...

Massachusetts Institute of Technology, MIT/Room E38-432 77 Massachusetts Ave., Cambridge, Massachusetts 02139-4307 * S Supporting Information ABSTRACT: The future availability of rare earth elements (REEs) is of concern due to monopolistic supply conditions, environmentally unsustainable mining practices, and rapid demand growth.

Mission 2016 - Massachusetts Institute of Technology

Rare earth elements (REEs) consist of the lanthanide series of the periodic table, as well as scandium and yttrium. Although vital for the manufacture of electronics, chemical catalysts, lasers, and many other high-demand products, these minerals are often difficult to locate, mine, and purify ("Rare earth elements," 2011).

Locations of Deposits - Massachusetts Institute of Technology

Demand for elements varies by element group (see Table 1) and the variety of strategic elements results in a similar variety of supply problems. For some elements, such as the rare earth elements (REEs), the problem is production.

Deep Sea Mining - Massachusetts Institute of Technology

Deep Sea mining, like asteroid mining, is a relatively unconventional method of extracting Rare Earth elements (REEs). Unlike asteroid mining, however, deep sea mining has already been undertaken through projects such as deep sea diamond mining. Actual mining for REEs has not been attempted because of environmental issues and cost.

This task is challenging because rare earth elements are used in small quantities, in a large number of components, and by suppliers far upstream in the supply chain. For this work, data on rare earth content reported by vehicle parts suppliers was assessed to estimate the rare earth usage of a typical conventional gasoline engine midsize sedan ...

Already mines in China release 9,600 to 12,000 cubic meters of toxic gas containing flue dust concentrate, hydrofluoric acid, sulfur dioxide, 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).

Rare-earth element - Wikipedia

The rare-earth elements, also called the rare-earth metals or (in context) rare-earth oxides, or the lanthanides (though yttrium and scandium are usually included as rare-earths) are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals. Scandium and yttrium are considered rare-earth elements because they tend to occur in the same ore deposits as the lanthanides and ...
