Eudialyte and catapleiite are both soluble in moderate strength sulphuric acid at room temperature and pressure, which has allowed for development of a simple flow sheet with low consumption of both reagents and energy.
The rare earth and zirconium bearing minerals at Norra Karr comprise almost exclusively the zirconosilicates: eudialyte and catapleiite.
2% of the sample, whilst the Zr-rich/REE-poor mineral catapleiite comprises 2.
Zr recovery was typically in the range 50% - 60% as some of the Zr-bearing mineral catapleiite reported to the non-magnetic fraction.
