AI Technical Summary
Existing methods for recovering lithium from brine are inefficient and costly due to the interference of high concentrations of other metal ions, instability in acid solutions, and impracticality in fixed beds, leading to frequent replacement and high operational costs.
A process using lithium ion sieves, such as titanium or niobium oxides, in powdered form, with controlled particle sizes and pH, combined with acid elution and solid/liquid separation, allows for continuous recovery of lithium by maintaining constant acid concentration and particle suspension, minimizing degradation and improving kinetics.
The process achieves over 90% lithium recovery with reduced impurities, enabling multiple reuse of lithium ion sieves and minimizing operational costs through efficient separation and regeneration, suitable for industrial-scale applications.
