Green and Efficient TBLS Process for Rare-Earth Element Recovery from Alkaline Rock-Carbonatite-Related Deposits

ACS Sustainable Chemistry & Engineering, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 7, 2025

Rare-earth elements (REEs) play a critical role in modern life and industry; however, conventional extraction methods for REEs from alkaline rock-carbonatite deposits are often environmentally challenging inefficient. In this study, we proposed newly green efficient process termed low-temperature thermal activation-noncontact bioleaching-biosorption (TBLS) the recovery of REEs. The bioleaching procedure involves two-step pretreatment ore with activation, followed by noncontact using metabolites secreted Aspergillus niger (A. niger). Under optimized conditions, TBLS achieved an impressive leaching efficiency 84.51%, which is over 40 times more than traditional methods. Additionally, separated cells A. demonstrated exceptional adsorptive capability, effectively capturing 800 mg/L Moreover, extracted leachate were selectively recovered niger, enabling regeneration recycling biolixiviant, thereby minimizing environmental impact. residue was found to be nontoxic, could reused leachate, further reducing harm. Characterization results revealed that mineral structure activation (thermal decomposition) metabolite effects (adsorption, dissolution, complexation) mainly involved process. This eco-friendly high-efficiency approach presents sustainable alternative
