Rare-earth element - Wikipedia

The rare-earth elements, also called the rare-earth metals or (in context) rare-earth oxides, or the lanthanides (though yttrium and scandium are usually included as rare-earths) are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals. Scandium and yttrium are considered rare-earth elements because they tend to occur in the same ore deposits as the lanthanides and ...

How are rare ea rths mined? - Lynas Rare Earths

When mined, rare earths are high lustre metals which are typically silver, silver-white, or grey in colour. When exposed to the air they tarnish and form oxide compounds. Rare earths, when found in a large enough cluster, are actually a ‘cocktail’ of elements which have to be separated into individual elements before they can be used commercially. Rare earths tend to be mined using open ...
