Ekanite is an uncommon silicate mineral with chemical formula Ca 2 ThSi 8 O 20 or (Ca,Fe,Pb) 2 (Th,U)Si 8 O 20. It is a member of the steacyite group. It is among the few gemstones that are naturally radioactive. Most ekanite is mined in Sri Lanka, although deposits also occur in Russia and North America.
More than 50 per cent of Ukraine’s critical rare earth mineral resources are in regions illegally annexed by Vladimir Putin and partially occupied by his forces.
Rare earths are a group of 17 metals used to make magnets that turn power into motion for electric vehicles, cell phones, missile systems and other electronics. There are no known substitutes.
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 ...
Loparite is a mineral that contains three rare elements: titanium, niobium, and tantalum. [28] This is why it is often mined, as it is considered a rare-earth mineral. [28] The deposits for loparite can be found in Russia and Paraguay, although it is also present in other countries such as Canada, Norway, Greenland, and Brazil. [29]
China is reportedly moving toward banning rare earth metal exports to keep high-tech advantages within the country.
Other minerals known to undergo metamictisation include allanite, gadolinite, ekanite, thorite and titanite. Ekanite is almost invariably found completely metamict as thorium and uranium are part of its essential chemical composition. Metamict minerals can have their crystallinity and properties restored through prolonged annealing.
“Green peas are a standout vegetable, offering a rare combination of 8 grams of fiber and 8 grams of protein per cup,” says Kimberly Jackson, M.P.A., RD, LD. “This dynamic duo plays a ...
