Concentrating rare earth elements to phosphate in

2021-2-15  The calcium phosphate phase tended to form dendritic crystals in the slag in the hotter zone. In the colder zone, calcium phosphate was more common as bulky particles forming around mullite. The bulky phosphate may have formed with Ca and Eu being rejected by the mullite formation while Al was resorbed by mullite.
