A Review of Rare Earth Elements Extraction with Emphasis

A Review of Rare Earth Elements Extraction with Emphasis

Sep 23, 2020 Furthermore, higher REE concentration in the coal ash samples could be the result of the low volatility of REEs during coal combustion and the subsequent even distribution in coal ashes [69,70,71]. Further magnetic separation experiments were performed by Lin et al. on the ash samples and found REE enrichment in the non-magnetic fraction [ 68 ].
