Ion-adsorbed　rare　earth　minerals　are　rich　in　medium　and　heavy　rare　earth　(RE),　which　are　important　strategic　resources.　In　this　article,　a　novel　approach　for　the　extraction　of　RE　from　ion　adsorbed　minerals　was　developed.　Through　a　comprehensive　assessment　of　their　extraction　and　separation　performance,　the　hydrophobic　deep　eutectic　solvents　(HDES)　with　a　composition　of　trioctylphosphine　oxide　(TOPO):　dodecanol　(LA):　2-thiophenoyltrifluoroacetone　(HTTA)　=　1:1:1　was　determined　as　the　optimal　configuration.　Under　optimized　conditions,　only　RE　were　extracted　by　the　HDES,　while　Al,　Ca,　Mg　were　not　extracted　at　all.　The　HDES　based　extraction　obviated　the　need　for　diluent　such　as　kerosene,　eliminating　the　generation　of　impurity　removal　residues.　The　RE　in　the　stripping　solution　could　be　successfully　enriched　by　saponified　lauric　acid,　achieving　an　impressive　precipitation　rate　of　99.7%.　The　RE　precipitate　underwent　further　enrichment,　resulting　in　a　RE　concentration　of　176　g/L　(REO　=　210　g/L).　Unlike　industrial　precipitants　such　as　oxalic　acid　and　ammonium　bicarbonate,　lauric　acid　can　be　effectively　recycled,　thereby　avoiding　a　large　amount　of　wastewater　and　carbon　dioxide　emissions.　The　obtained　RE　solution　product　exhibits　high　yield　and　purity,　this　study　provides　an　eco-friendly　and　high-yield　approach　for　extracting　RE.　©　2024　Elsevier　B.V.
