Immobilization of thallium and fluoride in lithium slag using low-cost cement-based stabilization systems

Key Points

• To evaluate the effectiveness of low-cost cement-based stabilization in immobilizing thallium and fluoride in lithium slag.
• Employed low-dosage cement stabilization techniques for lithium slag containing thallium and fluoride.
• Assessed contaminant mobility reduction based on binder dosage variations.
• Achieved a 54% reduction in contaminant mobility compared to higher-binder systems.
• Indicates low-dosage cement stabilization is cost-effective but requires further durability testing.
