Special Issue Information

Dear Colleagues,

We are excited to announce the second edition of our Special Issue entitled “Risk Assessment, Management, and Control of Mining Contamination”. This edition aims to address a comprehensive range of topics related to the heavy metal contamination of soils affected by mining activities, while placing a special emphasis on the innovative applications of Artificial Intelligence (AI), Machine Learning (ML), and Data Analytics.

Scope and Topics

This Special Issue seeks to publish a diverse collection of themed articles that explore both traditional and cutting-edge approaches to the assessment, management, and control of mining contamination. We welcome submissions that address the following topics, with particular interest in those incorporating Artificial Intelligence (AI), Machine Learning (ML), and Data Analytics:

1. Heavy Metal Contamination:

  • Identification and quantification of heavy metals in mining areas.
  • AI and ML applications for improved contamination assessment.

2. Ecological Risk Assessment of Heavy Metals:

  • Methodologies for assessing ecological risks.
  • AI-driven models for predictive ecological risk analysis.

3. Health Risk Assessment of Heavy Metals:

  • Evaluation of exposure and health risks.
  • ML algorithms and data-driven approaches to assessing health implications and risks.

4. Environmental Risk Assessment of Heavy Metals:

  • Comprehensive environmental risk assessment techniques.
  • Integration of data analytics and AI for risk modeling and environmental assessments.

5. Assessment of Heavy Metals' Geochemical Distribution:

  • Traditional and advanced geospatial analysis.
  • Data analytics and machine learning for geochemical distribution studies.

6. Availability of Heavy Metals:

  • Predictive modeling of metal bioavailability.
  • Traditional methods and ML-enhanced studies.

7. Mine Tailings' Metal Mobility:

  • Understanding and predicting metal mobility.
  • Dynamic modeling using data analytics.

8. Abandoned Mine Tailings:

  • Risk assessment and remediation strategies.
  • Traditional and AI-enhanced approaches to management.

9. Treatment of Acid Mine Drainage:

  • Traditional and innovative treatment technologies.
  • Predictive analytics for treatment efficiency.

10. Acid Mine Drainage Metal Removal Mechanisms:

  • Traditional methods and AI-driven improvements.
  • Data analytics applied to metal removal mechanisms.

We invite researchers and practitioners to submit original research articles, reviews, and case studies that align with the themes outlined above. Submissions should clearly demonstrate either traditional methods or the integration of AI, ML, or Data Analytics with the core domains of heavy metal contamination and risk assessment in mining contexts.

We look forward to receiving your contributions.

Mine tailings require careful monitoring and management, but traditional geochemical characterization methods are costly and time-consuming. This study demonstrates that magnetic properties can serve as effective proxies for predicting copper concentrations in mine tailings through an innovative spatial modeling approach. Analysis of magnetic and geochemical measurements from a Chilean copper mine tailing showed that magnetic properties combined with spatial modeling techniques could predict copper concentrations with high accuracy (R2 = 0.873 ± 0.085). The spatial distribution of magnetic properties revealed coherent patterns that effectively predicted geochemical characteristics. This approach substantially reduces characterization costs compared to traditional methods while maintaining accuracy. Our findings establish magnetic properties as valuable screening tools for tailings characterization, offering mining operations a cost-effective approach to environmental monitoring and management.

Extraction activities can have a significant impact on the environment due to the mobilization of trace elements. These elements can pose a risk to soils, biota, water, and human health when incorporated into nearby ecosystems. To evaluate the transfer of As, Cd, Pb, and Zn from mine areas to the marine environment, a study was conducted in the Cartagena-La Union mining district (SE Spain). The study area included the mouth of a stream affected by waste materials from tailing ponds. In addition, a maritime area without mining influence was selected as a control site. Sediment samples were collected (three transects with nine sampling points and three depths) at the El Gorguel shoreline, and analyzed for pH, electrical conductivity, total metal(loid)s content, water-soluble anions, and metal(loid)s in chemical fraction distribution. Water and biota samples (Paracentrotus lividus, Patella vulgata, Hexaplex trunculus, Anemonia viridis, and Trachinotus ovatus) were also collected for metal(loid) content analysis. The results showed that the metal(loid)s concentration in the sediment increased compared to the control site, which was not influenced by mining activities. The chemical composition of metal(loid)s in the sediments revealed that Cd is the most hazardous element due to its high concentration in the labile fractions (20%), suggesting easy transfer to the marine environment. However, transfer mechanisms should be studied in various scenarios with different climatic, wave, and tidal conditions. Marine biota metal(loid)s concentrations showed an increase in specimens collected under the influence of mining activities but without exceeding limits that would affect incorporation into the trophic chain. Consequently, bioaccumulation and biomagnification processes must be considered in a future biomonitoring program. Full article
