- •
First LCA study on REOs production from ion adsorption clay.
- •
Processing ion adsorption clays has higher eutrophication vs bastnasite/monazite.
- •
Processing ion adsorption clays has lower acidification vs bastnasite/monazite.
- •
Individual REO from ion adsorption clay tend to have lower impacts.
- •
Ammonium sulfate and oxalic acid are two major contributors.
