The Yangtze River, the longest river in Asia, was once home to two species of dolphin—the finless porpoise and the Baiji dolphin. However, due to man-made environmental changes, the Baiji dolphin went extinct in 2006. Its brethren, the finless porpoise, is known for possessing a mischievous smile and the heightened intelligence of a gorilla. Aug 01, 2018Rare earth elements really aren't that rare; they're just rarely mined. Many in Washington, D.C., particularly those in the Defense Department, see this as a major looming issue. That's because the Mountain Pass mine just on the California side of the border with Nevada southwest of Las Vegas closed in 2015 when its operator went bankrupt.

10 Rarest And Amazing Astronomical Events

In every 30 Earth years a huge storm formation will occur in the Northern hemisphere of Saturn. This rare astronomical event is known as great white thunder storm. This ammonia rich cloud formation causes by strong thunder and lightning. This cloud formation has a length of half of diameter of Earth.

Rare earth element occurrences in the United States. Detailed descriptions of more than 200 mineral districts, mines, and mineral occurrences (deposits, prospects, and showings) within the United States that are reported to contain substantial enrichment of rare earth elements.

Aug 19, 2015The last few years have been a turbulent time for the rare earths market. This group of 17 elements, which have become vital in the manufacturing of high-tech products ranging from military jet components and hybrid cars to wind turbines and smartphones, aren't all that rare, but their geological distribution is such that there are relatively few deposits of rare earth-bearing minerals that

Rare Earths include the unique elemental group known as the Rare Earth Elements (REE's). Historically the term 'rare earths' has been applied to the lanthanide group of elements, which range from Lanthanum (atomic number 57) to Lutetium (atomic number 71), plus Scandium (atomic number 21) and Yttrium (atomic number 39), which have similar properties.

Mar 05, 2015Meet The Rarest Natural Element on Earth . BEC CREW . 5 MARCH 2015 . Named after the Greek word for unstable (astatos), Astatine is a naturally occurring semi-metal that results from the decay of uranium and thorium. In its most stable form - astatine-210 - it's got a half-life of just 8.1 hours, which means even if you did happen to stumble on

Is Mining Rare Minerals on the Moon Vital to National

The seemingly barren moon may actually be a treasure-trove of priceless resources: a potentially bountiful, mineral-rich – yet untapped – cosmic quarry. Still, few see the moon as an alluring mining site, ripe for the picking of rare elements of strategic and national security importance. Here on Earth, China recently blocked the export of rare earth elements to Japan for use in an array

Rare earths may be everywhere, but it is nonetheless difficult to separate them from other similar elements and purify them. There are very few places in the world that separate rare earths, namely France and China, and the United States is working on it. The separation process yields a rare earth

The rare earth elements (REE) are fifteen elements with atomic numbers 57 through 71, from lanthanum to lutetium ("lanthanides"), plus yttrium (39), which is chemically similar to the lanthanide elements and thus typically included with the rare earth elements.

The term "Rare Earth" originates from Rare Earth: Why Complex Life Is Uncommon in the Universe (2000), a book by Peter Ward, a geologist and paleontologist, and Donald E. Brownlee, an astronomer and astrobiologist. An alternative viewpoint was argued by Carl Sagan and Frank Drake, among others. It holds that Earth is a typical rocky planet

Nov 20, 2002Rare Earth Element Abundances "Rare" earth elements is a historical misnomer; persistence of the term reflects unfamiliarity rather than true rarity. The more abundant REE are each similar in crustal concentration to commonplace industrial metals such as chromium, nickel, copper, zinc, molybdenum, tin, tungsten, or lead (fig. 4).

Jan 01, 2016The rare earth elements (REE) are a group of 17 chemically similar elements (the lanthanides, scandium (Sc), and yttrium (Y)). Here we focus on the lanthanides and Y, which behave in similar ways in most environments in the Earth's crust. They are typically divided into light rare earth elements (LREE) and heavy rare earth elements (HREE).

A brief overview including uses, worldwide resources, and

The rare-earth elements are often informally subdivided into "heavy rare earths" and "light rare earths" based on the atomic number of the element. Lanthanum, cerium, praseodymium, neodymium, promethium and samarium, with atomic numbers 57 through 62, are generally referred to as the "light rare

In addition, some users have been known to project their inner energy outwards in a lethal blow of force or create optical illusions and tricks of the mind by accessing the spiritual plane. How the powers present themselves will depend on the channeling of the user. In order to become one of the strongest weapons on planet Earth, you don

Rare-earth element, any member of the group of chemical elements consisting of three elements in Group 3 ( scandium [Sc], yttrium [Y], and lanthanum [La]) and the first extended row of elements below the main body of the periodic table ( cerium [Ce] through lutetium [Lu]). The elements cerium through lutetium are called the lanthanides, but many scientists also, though incorrectly, call those elements

Zimbabwe sits on bountiful and lucrative deposits of minerals known as rare-earth elements (REE), some of which sell for more than US$1 000 for a single kilogram and where investors are seeking alternative sources to China, which dominates production. The 17 rare earth elements are used in the manufacture of glasses, electronics, hybrid vehicles, wind

A rare and scarce earth metal known as Neodymium is used in many consumer and military products including smartphones, smart bombs, laptop computer monitors, and electric/hybrid cars. In one year's time, the price of Neodymium has gone from $19/lb. to $129/lb.
