The Potential of Iron Ore Tailings as Secondary Deposits of Rare MDPI
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 to close to the grade of raw ore . The rest are stored in tailing dams as a secondary resource causing pollution and environmental risks.
