01/05/2021· In the wet process, roughly 80% of the REE present in the apatite are absorbed during formation of the PG (Al-Thyabat and Zhang, 2015). The REE content of PG varies from 0.04% to 0.50% (Hammas-Nasri et al., 2019; Lütke et al., 2020). REE separation and purification from acid leachate is more challenging than dissolution of REE from PG.
