· Pioneering new research has helped geologists solve a longstanding puzzle that could help pinpoint new, untapped concentrations of some the most valuable rare earth deposits. A team of geologists, led by Professor Frances Wall from the Camborne School of Mines, have discovered a new hypothesis to predict where rare earth elements neodymium and dysprosium .
· Rare Earth: Afghanistan Sits on 1 Trillion in Minerals. Afghanistan may be sitting on one of the richest troves of minerals in the world, valued at nearly 1 trillion, scientists say. This ...
· Xenotime deposits (xenotime is a rare earth phosphate mineral which is a rich source of yttrium and heavy rare earths) in Madhya Pradesh, carbonatitealkaline complex in Ambadongar, Gujarat, polymetallic mineralization in Siwana Ring Complex, Rajasthan (Banerjee et al., 2014) are some of the promising areas for REE exploration and exploitation.
· How rare earth minerals form in carbonatite deposits isn't understood by scientists, so it's very possible that rare earth minerals could form in other types of deposits in ways currently ...
In total the three deposits contain approximately 270,000 tonnes of uranium and 11 million tonnes of rare earth oxide. The Kvanefjeld deposit is the largest and most rigorously defined of the three deposits and as a result it is this deposit that is the focal point of studies to evaluate the feasibility of mining and processing for the project.
Xenotime preferentially incorporates heavy rare earth elements (HREEs) while monazite incorporates light rare earth elements (LREEs). This is important because LREEs are much more readily available and therefore a xenotime deposit may be more valuable than a deposit .
· Carbonatiteassociated rareearthelement (REE) deposits are the most significant source of the world's REEs; however, their genesis remains unclear. Here, .
Rare Earth Ore Classifiion. Classifiion of ores related to alkaline rocks is also controversial. Table 2 presents a relatively simple classifiion that follows analogous egories for deposits related to nonalkaline igneous rocks. Some of the more unusual alkaline rocks that host, or are related to, REE ores are carbonatite and phoscorite, igneous rocks composed principally of ...
· There are also rare earth minerals and, perhaps most importantly, what could be one of the world's biggest deposits of lithium — an essential .
Rare earths and thorium are the principal commodities of interest in these deposits. Total rareearth content of these samples ranged from 47 to 27,145 ppm (parts per million), and the thorium content from to 990 ppm. The amount of total rare earths of individual samples shows little correlation with that of thorium.
· President Biden's hasty exit from Afghanistan and the Taliban's rapid takeover left the in a tough spot for getting at the country's rare earth minerals, while China positioned itself to .
· Vast deposits of rare earth minerals, crucial in making hightech electronics products, have been found on the floor of the Pacific Ocean .
These deposits are characterized by low grades ( wt% rare earth oxide; REO) and individually small tonnages (<10 kt REO resources), except the superlarge Zudong deposit (Xie et .
· "Since heavy rare earth elements are becoming increasingly scarce on the world market, the discovery of fayalite as a new potential source for loing new deposits of rare earths .
Data on rare earth (including yttrium) mines, deposits, and occurrences were compiled as part of an effort by the USGS and the University of Arizona Center for Mineral Resources to summarize current knowledge on the supply and demand outlook and related topics for this group of elements. Economic competition and environmental concerns are increasingly constraining the mining and .

Uranium from Rare Earth Deposits. (Updated August 2021) A large amount of uranium is in rare earth deposits, and may be extracted as a byproduct. Higher uranium prices and geopolitical developments would enhance the economic potential for recovering these. Rare earths are essential for many modern technologies.
