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.

How Rare

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 elements range in crustal abundance from cerium, the 25th most abundant element of the 78 common elements in the Earth's

Rare Earths

As we noted, although originally thought to be rare, many of the Rare Earth Element (REE) minerals are actually common in the Earth's crust. However, these elements rarely exist in pure form; they are usually found within other minerals, making them difficult to extract from the ore and costly to mine.

Regolith

Feb 16, 2021· The Wicheeda project has indicated mineral resources of 4,890,000 tonnes averaging 3.02% LREO (Light Rare Earth Elements) and inferred mineral resources of 12,100,000 tonnes averaging 2.90% LREO 2.

Environmental Damage

However, mineable concentrations are less common than for most other ores. The main economic minerals exploited for their rare earth content are: Bastnaesite (CeFCO 3) A fluoro-carbonate of cerium containing 60–70% rare earth oxides (REO) including lanthanum and neodymium. Bastnaesite is the world's major source of rare earths.
