This element is used in camera and telescope lenses. It also takes more chemicals to separate uranium and thorium than it does to separate base metals such as copper. The rare earth elements (rees) are comprised of the lanthanide elements plus scandium and yttrium, which have similar physical properties and are properties and applications.

All are metals and have many similar properties which often cause them to be found together in geologic deposits.

Rare earth availability is undergoing a temporary decline due mainly to quotas being imposed by the chinese government on export and action taken against illegal mining operations. The materials are actually not rare, despite their name, but they are difficult to find in the elements are often referred to as rare earth oxides because many of them are typically sold as oxide compounds. They are exploited in a range of new technologies along with elements such as y, nb, ta, zr, hf and sc with which they are intimately associated in many deposits. It also takes more chemicals to separate uranium and thorium than it does to separate base metals such as copper.

This chart shows a history of rare earth element production, in metric tons of rare earth oxide equivalent, between 1950 and 2020.

However, they're usually bound up with other elements, like uranium and thorium, and require laborious.

The rare earth elements (ree) are a set of seventeen metallic elements.

There are military applications for seven of the heavy rare earths:

However, they're usually bound up with other elements, like uranium and thorium, and require laborious.

Also, since the rare earth elements are metals, they are often called rare earth metals (rem) or rare earth metal oxides (remo).
