rare earth ore classification. classification of ores related to alkaline rocks is also controversial. table presents a relatively simple classification that follows analogous categories 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 the rare earth elements have become vital to manufacturing numerous high-tech products, which has been accompanied by a large increase in their demand. At the same time, there has been concern by the united states and many other nations about the near-monopoly of mining, processing, and supply of rees from one nation, china.

as alkaline volcanic and intrusive rocks. a long process involving mining, crushing and we can overcome the technical challenges of rare earth mining and extraction in an environmentally the center of rare-earth mining there is baotou, a city in inner mongolia with 2.3 million residents thats become something of a poster child for minings ecological wreckage.
this poses a problem, of course. extracting the rare earth elements used in "green" tech is flagrantly dirty. radioactive minerals such as uranium and thorium are concentrated in the waste rock and sludge produced during mining. then processing the rare earth minerals causes more severe damage to the land source: epa. since the most of this means that the metal concerns of hardrock mining also apply to rare earth mining. In particular, the elements of concern at rare earth mines include, but are not limited to, aluminum, arsenic, barium, beryllium, cadmium, copper, lead, manganese, and zinc.lead, manganese, and zinc
