In doing so, we quickly found reporting on rare earths to be especially challenging. To begin with, we had to learn how rare earths are different from other metals and minerals like iron or copper.
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 rare earth elements (REEs) are 15 elements that range in atomic number from 57 (lanthanum) to 71 (lutetium); they are commonly referred to as the lanthanides. Yttrium (atomic number 39) is also commonly regarded as an REE because it shares chemical and physical similarities and has affinities with the lanthanides.
Though it has a key role in the rare earths space, China has long had problems with illegal rare earths mining. Industrial Minerals reported in January 2017 that the country would have until April
What Happened to the Rare Earths Crisis? Four years ago, manufacturers fretted that trade controls in China would lead to a shortage of materials used in making an array of technology products.
Critical Minerals Alaska Rare Earths February 26, 2018 By News Team Rare earth elements are key ingredients in a wide range of modern products such as terabyte hard drives that fit in the palm of your hand, high efficiency power generation and sophisticated military hardware.
A rare earth mineral contains one or more rare earth elements as major metal constituents. Rare earth minerals are usually found in association with alkaline to peralkaline igneous complexes, in pegmatites associated with alkaline magmas and in or associated with carbonatite intrusives .
What Are Rare Earths? Rare earths are a series of chemical elements found in the Earths crust that are vital to many modern technologies, including consumer electronics, computers and networks, communications, clean energy, advanced transportation, health care, environmental mitigation, national defense, and many others.

Rare earths typically occur as trivalent cations in rock forming minerals in carbonates, oxides, phosphates, and silicates. REE are chemically similar to thorium and are often found in minerals and rocks in association with this element.

Rare earths elements are also being used for a growing number of applications. At the forefront of this wave of discovery are new technologies being developed for computer science uses, industrial engineering, renewable energy sciences and military applications.
The principal economic sources of rare earths are the minerals bastnasite, monazite, and loparite and the lateritic ion adsorption clays. The rare earths are a relatively abundant group of 17 elements composed of scandium, yttrium, and the lanthanides.
The rare earths industry in China continued its consolidation into six major industrial entities. At midyear, the consolidation and efforts to stem illegal production activity were reported to have bolstered prices of some rare earth materials; however, by yearend, producers in China

Rare earth elements bearing minerals, once separated, contain as many as 14 individual rare earth elements (lanthanides and yttrium) that must be further separated and refined. The complexity of extracting and refining rare earth elements is illustrated by a metallurgical flow sheet for the Mountain Pass mine in California (fig. 2).

Boom in Mining Rare Earths Poses Mounting Toxic Risks The mining of rare earth metals, used in everything from smart phones to wind turbines, has long been dominated by China. But as mining of these key elements spreads to countries like Malaysia and Brazil, scientists warn of the dangers of the toxic and radioactive waste generated by the mines and processing plants.
The Common Rare Earths Bearing Minerals. In rock forming minerals, rare earths typically occur in compounds as trivalent cations in carbonates, oxides, phosphates, and silicates. The most common minerals are shown in the list below which is far from comprehensive.
