Discussion

This study demonstrates lithium's co-enrichment with aluminium and explores mineral transformation patterns.

Lithium enrichment in clay-bauxite shows a strong relationship with aluminium and magnesium, influencing mineral transformations.
Transformations like kaolinite to illite may cause lithium loss through potassium-lithium substitution, complicating enrichment.
19F NMR results show distinct interactions between lithium and mineral structures, with significant shifts indicating complex binding.
The study indicates high leaching efficiency of lithium from minerals using a 200°C-H2SO4 solution, promoting eco-friendly recovery.

Song et al. (2025) studied this question.
