Iron ore - Wikipedia
Metallic iron is virtually unknown on the surface of the Earth except as iron-nickel alloys from meteorites and very rare forms of deep mantle xenoliths.Some iron meteorites are thought to have originated from accreted bodies 1,000 km in diameter or larger. The origin of iron can be ultimately traced to formation through nuclear fusion in stars and most of the iron is thought to have ...

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 ...

The deposit is mainly exploited for its iron ore, and only about 10% to 15% of the rare earth content is recovered; due to this low percentage, the average REE law of tailing has been increased from 6.8% to 8.85%, close to the grade of raw ore . The rest are stored in tailing dams as a secondary resource, causing pollution and environmental risks.
