The recent tailings storage facility (TSF) dam failures recorded around the world have concerned society in general, forcing mining industry to improve its operating standards, invest greater economic resources, and implement best available technologies (BATs) control TSFs for safety purposes avoid spills, accidents, collapses. In this context, as era of digitalization Industry 4.0 continues, monitoring based on sensors become increasingly common industry. This article studies state art implementing sensor monitor structural health management issues TSFs, highlighting advances experiences through a review scientific literature topic. methodology applied adheres Preferred Reporting Items Systematic Reviews Meta-Analyses (PRISMA) guidelines utilizes maps data visualization. To do so, three steps were implemented: (i) quantitative bibliometric analysis, (ii) qualitative systematic literature, (iii) mixed integrate findings from (ii). As result, presents main advances, gaps, future trends regarding characteristics TSF digitalization. According results, existing research predominantly investigates certain technologies, such wireless real-time monitoring, remote (RS), unmanned aerial vehicles (UAVs), survey vessels (USVs), artificial intelligence (AI), cloud computing (CC), Internet Things (IoT) approaches, among others. These stand out their potential mine tailings, which is particularly significant context climate change-related hazards, reduce risk failures. They are recognized emerging smart solutions with reliable, simple, scalable, secure, competitive characteristics.

The management of mine tailings presents a global challenge. Re-mining these to recover remaining metals could play crucial role in reducing the volume stored tailings, as historical mining methods were less efficient than those used today. Consequently, wastes have potential become unconventional resources for critical minerals. To assess this potential, minerals and investigated through sampling, characterization, 3D geostatistical modeling. Bleïda copper Morocco modeled, residual estimated using ordinary kriging (OK). Tailings systematically sampled at depth 1.8 m triangular grid tubing method. metallic mineralogical content samples was analyzed, numerical model tailing’s facility created topographic drone surveys, geochemical data, results from block reveal that deposited is 3.73 million cubic meters (mm3), equivalent 4.85 tonnes (Mt). Furthermore, based on average grade (~0.3% by weight) studied part pond, are 2760 tonnes. Mineralogical characterization indicates mainly associated with sulfide carbonate minerals, which exhibit low degree liberation. This study aims serve reference assessing reprocessing feasibility both abandoned active mines, thereby contributing sustainable facilities. Geostatistical modeling has proven effective producing tonnage estimates storage facilities should be adopted industry reduce technical financial uncertainties re-mining.

Phosphate mining generates substantial quantities of waste rock during the extraction sedimentary ores, leading to significant environmental concerns as these wastes accumulate around sites. The industry is under increasing pressure adopt more sustainable practices, necessitating considerable financial investments in remediation and technological advancements. Addressing challenges requires a holistic strategy that balances social responsibility, preservation, economic viability. This study proposes an innovative, cost-effective, environmentally friendly method manufacture compressed stabilized earth bricks by combining valorization phosphate (PWR) washing sludge (PWS). These offer numerous advantages, including low embodied energy, robust mechanical performance, excellent insulation thermal properties. Initially, Toxicity Characteristic Leaching Procedure (TCLP) test radiometric surface contamination measurement, carried out on raw materials (PWR PWS), showed results were below permissible limits. Then, chemical, mineralogical, geotechnical properties characterized. Subsequently, various mixtures formulated laboratory using PWR PWS, with without cement stabilizer. Optimal formulations identified scaled up for pilot production solid dimensions 250 × 125 75 mm3. resulting exhibited conductivity water absorption coefficients satisfied standard requirements. not only addresses issues associated but also provides solution building production.
