Rare Earth Element Extraction Efficiency from Coal Fly Ash

89.16% leaching efficiency was achieved for rare earth elements using microwave-assisted deep eutectic solvents. The dataset likely contains experimental results from a study by Changquan Men, published on figshare in May 2026. It describes a process using three synthesized solvents to recover strategic materials from industrial byproducts.

Use Cases

• Benchmarking leaching efficiency of different solvents based on the reported 89.16% performance.
• Analyzing the impact of solvent acidity and ionization degree on extraction selectivity.
• Modeling the protonation and coordination mechanisms described for REE recovery.
• Comparing microwave-assisted DES processes with conventional hydrometallurgical methods.

Strengths

• Includes a specific leaching efficiency result of 89.16% under optimized conditions.
• Describes three synthesized solvents (ChCl–PTSA, lactic acid, formic acid) and their comparative performance.
• Provides mechanistic insights from FT-IR and ¹H NMR analyses.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 22.7 MB size suggests a small dataset, potentially limiting statistical analysis.
