Rare Earths: The Hidden Cost to Their Magic
The 17 rare earth elements are often called the spices or vitamins of industry. While we don't need much of them, they're sprinkled in small amounts through our most powerful, futuristic, and dare we say it, magical tools. They power our iPhones and computers; they're in wind turbines and hybrid cars.

US Army to process Rare Earths | Current Affairs - IAS Parliament
Rare Earth Elements or Rare Earth Metals are a set of 17 chemical elements in the periodic table. They comprise the 15 lanthanides along with the scandium and yttrium, which tend to occur in the same ore deposits as the lanthanides, and have similar chemical properties. Despite their classification, most of these elements are not really "rare".

Rare Earth Extraction - an overview | ScienceDirect Topics
Oxalic acid used to precipitate rare earth (s) could separate rare earth (s) effectively from aluminum, but its consumption would increase by comparison with nonaluminum rare earth (s), because oxalic acid can complex with Al 3 + to consume oxalic acid, so excess dosage of oxalic acid is required to precipitate rare earth (s) with high recovery.
