Special Issue Information

Dear Colleagues,

The generation of mine tailings worldwide increases every year due to the rising demand for certain metals that are necessary for the decarbonization of the economy, which will be achieved by developing the digital age of information, implementing electromobility, and inserting renewable energies in order to face the global crisis of climate change. It is in this scenario that mine tailings management with the best available technologies (BATs) becomes a crucial issue in carrying out responsible practices and thus achieving sustainability within the mining business.

This Special Issue arises from the consideration of the insertion of a new paradigm on mine tailings management and the emergence of green mining solutions to satisfy responsible mining needs for a sustainable society. We invite researchers, professors, scientists, consultants, mining practitioners, and technology suppliers to submit their latest research work and share their experiences with other colleagues. We welcome research articles and reviews of research studies that focus on this important and complex issue from a multidisciplinary perspective.

The present Special Issue aims to collect innovative and ground-breaking achievements in different aspects of green mining solutions applied to sustainable and resilient mine tailings storage facilities. The key areas include, but are not limited to, the following:

(1) Mine tailings co-disposal;
(2) Mine tailings dewatering;
(3) Filtration of mine tailings;
(4) Dry stacking of mine tailings;
(5) Underground mine backfilling with mine tailings;
(6) In-pit disposal of mine tailings;
(7) Mitigation of mine tailings dust emission;
(8) Resilience and adaptation against climate change within mine tailings storage facilities;
(9) Circular economy and green reprocessing of mine tailings;
(10) Innovative use of treated mine tailings in society;
(11) Phytoremediation of mine tailings;
(12) Landscape rehabilitation of mine closure of tailings storage facilities;
(13) Sustainable management of abandoned mine tailings storage facilities;
(14) Socio-environmental rehabilitation of territories affected by a mine tailings dam failure;
(15) Sustainable geochemical management to mitigate acid rock drainage in mine tailings.

We welcome your contributions.

In this article, a numerical calibration procedure for undrained cyclic triaxial tests is presented to evaluate the liquefaction potential in sand and silt samples from mining tailings in northern Chile. The numerical modeling of an axisymmetric specimen involved two stages: isotropic consolidation using the Hardening Soil Small (HSS) model and a cycling phase employing the UBC3D-PLM model to simulate the onset of liquefaction using the criterion that the excess pore pressure ratio Ru should exceed 0.8. The results demonstrate that the UBC3D-PLM modeling calibrated with experimental data from cyclic triaxial tests effectively represents the excess pore pressure in both sandy and silty soils from mining tailings. The accuracy of the modeling decreases when a single set of parameters is applied to the same soil at different cyclic stress ratios (CSR), highlighting the need for specific calibrations for each loading.
