Lithium　is　a　critical　mineral　resource.　With　the　development　of　high-end　manufacturing　industry,　the　demand　for　high-performance　lithium-containing　chemical　raw　materials　continues　to　grow.　At　present,　lithium　needs　to　be　acquired　from　a　large　amount　of　lepidolite　ore,　constrained　by　the　existing　lithium　resource　supply　limitation　quandary,　and　the　industry　urgently　needs　to　develop　more　efficient　beneficiation　and　extraction　methods　for　lepidolite.　Findings　have　suggested　mixed　collectors　(e.g.,　DDA/SDBS)　achieve　a　4.99%　Li2O　grade　and　98%　recovery　at　neutral　pH,　reducing　reagent　use　by　20–30%.　Microwave-assisted　roasting　boosts　Li　recovery　to　95.9%　and　cuts　energy　use　by　26.9%.　Bioleaching　with　Acidithiobacillus　ferrooxidans　(A.F.)　and　rhamnolipid　releases　6.8　mg/L　Li　with　a　lower　environmental　impact.　Sulfuric　acid　baking　recovers　Li　(97.1%),　Rb　(96.0%),　and　Cs　(95.1%)　efficiently.　Despite　challenges　in　fine-particle　recovery　and　reagent　costs,　integrated　strategies　like　nanobubble　flotation,　green　collectors,　and　AI　optimization　offer　sustainable,　high-efficiency　extraction.　This　work　provides　insights　for　advancing　lepidolite　processing,　balancing　economics　and　environmental　stewardship.　©　2025　by　the　authors.
