What method is used to separate rare earth metals

Open in App

Solution

Dear Student,

Hydrometallurgy is one of the methods for such separation. It is divided into 3 segments

1. Leaching
2. Concentration and purification of solution
3. Recovery of metal/ metal compound

The third step can be done by electrolysis or precipitation.

Most recently, David Clarke and William Bonificio devised a new method to separate rare earth metals by using bacteria filters and solutions with pH around 3.
