MICP Treatment Data for Rare Earth Tailings Strength and Leaching

A study by Zhongqun Guo employed microbially induced carbonate precipitation (MICP) to solidify ion-adsorbed rare earth mining tailings. The dataset, last updated in May 2026, contains experimental results measuring unconfined compressive strength up to 770 kPa and heavy metal leaching concentrations. It investigates the effects of treatment method, cementation solution concentration, and initial heavy metal contamination levels.

Use Cases

• Modeling the relationship between calcium carbonate content and unconfined compressive strength based on experimental results.
• Analyzing the effect of cementation solution concentration on heavy metal leaching behavior described in the study.
• Evaluating the performance of MICP treatment across different initial heavy metal contamination levels.
• Studying the microstructural mechanisms of heavy metal immobilization through precipitation, adsorption, and encapsulation.

Strengths

• Includes specific quantitative results such as a maximum unconfined compressive strength of 770 kPa.
• Reports detailed experimental conditions including cementation solution concentrations up to 1.00 mol/L and heavy metal contamination levels up to 500 mg/kg.
• Provides microstructural analysis findings on the primary cementing phase.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 5.5 KB, indicating limited scope.
