Efficient　removal　of　iron　and　aluminum　impurities　is　critical　for　the　extraction　of　lithium　and　rubidium　from　zinnwaldite,　a　lithium-bearing　mineral.　In　this　study,　solvent　extraction　using　P507　was　employed　to　remove　iron　and　aluminum　from　zinnwaldite　leaching　solutions.　However,　stripping　iron　from　the　organic　phase　proved　challenging　due　to　the　strong　interaction　between　iron　ions　and　the　extractant.　To　address　this,　a　novel　reduction　stripping　method　was　developed　using　ascorbic　acid　(AA)　as　a　reductant.　This　method　exploits　the　reduction　of　Fe3+　to　Fe2+　in　the　aqueous　phase,　weakening　the　binding　between　iron　ions　and　the　organic　phase,　thus　enabling　efficient　stripping.　The　optimized　process　achieved　over　99.99%　removal　of　iron　and　aluminum　impurities.　Subsequently,　rubidium　was　selectively　extracted　using　t-BAMBP,　with　a　total　recovery　rate　of　88.53%.　Scaling-up　experiments　confirmed　the　feasibility　of　the　process　for　industrial　applications,　demonstrating　high　efficiency　and　reagent　recyclability.　This　study　offers　a　promising　approach　for　the　efficient　extraction　and　separation　of　valuable　metals　from　zinnwaldite,　with　potential　for　broader　applications　in　metal　processing.
