Alkaline igneous rocks form from cooling of magmas derived by small degrees of partial melting of rocks in the earths mantle. the formation of alkaline rocks is complex and not fully understood but can be thought of as a geologic process that extracts and concentrates those elements that do not fit into the structure of the common rock-forming.

Its amazing good fortune, then, that out in the barren scrub of far west texas 85 miles east of el paso, an unassuming 1,250-tall mountain called round top holds the promise of making america largely self-sufficient in these critical minerals. the mountain contains five out of six light rare earths such as neodymium, 10 out of 11 heavy rare earths dysprosium, for example, and all five permanent magnet materials. whats more, round top has large deposits of lithium, critical for batteries in evs and power storage.

Read MoreOut in the mojave desert in california lies the mountain pass mine, once the worlds foremost supplier of valuable rare earth minerals 17 elements deemed critical to modern society. in an age where china controls 80 percent of the global output of these minerals, it is strange to believe that a once-dominant source sits within the united states. stranger still is the tale of how this mine came to supply the chinese rare earths industry.
Read MoreIn 1952, mountain pass opened. first explored as a uranium deposit, it soon supplied rare earths for the electronic needs of the cold war economy. until the 1990s, it stood alone as the only major source of rare earths worldwide.
Read MoreBy 2002, however, the mine was defunct. in the eyes of the u.s. government and major manufacturers, it no longer made sense to acquire rare earths from a u.s. source subject to stringent environmental regulations. instead, the hard business of extracting useful minerals was exported to other countries, where environmental damage was safely out of sight. china happily obliged, allowing environmental harm to proliferate so long as the costs of rare earth mining were kept down.
Read MoreIn 2008, a group of investors formed molycorp and convinced wall street to resurrect mountain pass under an audacious plan dubbed project phoenix. with the promise of wealth to be generated from new but untested technologies, molycorp bullishly claimed that it could compete with or even underprice chinas near-monopoly. molycorps critics werent convinced, pointing to the immaturity of the companys mineral separation technology, the high barriers to entry and the lingering threat of the chinese monopoly to manipulate prices at will.

Read MoreThe estimated average concentration of the rare earth elements in the earths crust, which ranges from around 150 to 220 parts per million table 1, exceeds that of many other metals that are mined on an industrial scale, such as copper 55 parts per million and zinc 70 parts per million. unlike most commercially mined base and precious metals, however, rare earth elements are rarely concentrated into mineable ore deposits.
Read MoreThe principal concentrations of rare earth elements are associated with uncommon varieties of igneous rocks, namely alkaline rocks and carbonatites. potentially useful concentrations of ree-bearing minerals are also found in placer deposits, residual deposits formed from deep weathering of igneous rocks, pegmatites, iron-oxide copper-gold deposits, and marine phosphates table 2.

Read MoreWeathering of all types of rocks yields sediments that are deposited in a wide variety of environments, such as streams and rivers, shorelines, alluvial fans, and deltas. the process of erosion concentrates denser minerals, most notably gold, into deposits known as placers. depending on the source of the erosion products, certain rare earth elements-bearing minerals, such as monazite and xenotime, can be concentrated along with other heavy minerals.
Read MoreThe source need not be an alkaline igneous rock or a related rare-earth deposit. many common igneous, metamorphic, and even older sedimentary rocks contain enough monazite to produce a monazite-bearing placer. as a result, monazite is almost always found in any placer deposit. however, the types of placers with the greatest concentrations of monazite are typically ilmenite-heavy mineral placers, which have been mined for titanium oxide pigments, and cassiterite placers, which are mined for tin.
Read MoreRare-earth element - rare-earth element - abundance, occurrence, and reserves as noted above, the rare earths are fairly abundant, but their availability is somewhat limited, primarily because their concentration levels in many ores are quite low less than 5 percent by weight. an economically viable source should contain more than 5 percent rare earths, unless they are mined with another ...
