Our industry analysis tells us that the practice of dewatering tailings is still limited to few areas globally. Only ~5% of tailings generated in 2018 were dewatered into thickened, paste, or dry tailing. We estimate that by 2025 the share of generated tailings that are dewatered will increase to ~13%.
responsibility of the mine owner. Tailings facilities typically occupy 10 to 40 per cent of the area of a reclaimed mining landscape, with pits and waste rock dumps responsible for most of the ... by the downstream method, which receive regular depositions. For some dams with active pouring above reclaimed areas, line spills and deposition ...
The contamination of heavy metals (HMs) from the abandoned mine tailings is one of the most severe environmental problems in mining areas, especially in southern China (Tao et al. 2019; Zeng et al. 2013), where large amounts of HM-contained molybdenum (Mo) tailings are produced from over thousands of open-pit mines in China (Wang et al. …

1.1 Sphericity. Sphericity is defined as the ratio of the surface area of a sphere (equal volume of the particle) to the surface area of the particle; this concept was initially named as the correct degree of sphericity (Wadell 1933).Due to the difficulty of obtaining this value in a three-dimensional way, it was presented in a two-dimensional …
Bio-hydrometallurgical methods such as bioleaching, which is one of the cheapest and most environmentally friendly methods for metal recovery from low-grade resources [181], offers a more promising reprocessing option for the treatment of mine tailings and we believe it deserves greater attention and consideration. However, slow …

The paste tailings disposal method produces a high viscosity, non-Newtonian fluid, characterised by paste copper tailings of 65-80% solid weight concentrations (Cw) and a water recovery rate of ...
The tailings dam of the Cadia gold mine (see Fig. 1) had the highest footprint in term of the LUC value among the other gold mine tailings dams. This dam failed in 2018 and released a substantial amount (i.e., ~1.3 Mm 3 ) …
Whether driven by regulatory compliances, tailings dam failure and water scarcity, mine tailings can well become a strong business case in the near future. Due to growing mining volumes, global tailings generation was estimated to total ~3.2 bn tons for copper and ~1.8 bn tons for iron in 2018.
Mineral waste can be defined as a material leftover from exploration, mining and quarrying operation that cannot find a productive use. It is the high-volume material that originates from the excavation and physical and chemical processing of a wide range of metalliferous and non-metalliferous minerals by opencast and deep shaft methods …
Mine tailings (MTs) are pulverized ... There is growing recognition that MTs represent an underutilized secondary resource that could deliver substantial value through reprocessing and comprehensive utilization [9]. ...

Although tailing storage in ponds constructed by closing a valley or watershed from a river using a dam or an embankment may be considered as the most widely used method in the world for tailings disposal (Real & Franco, 1990), other established methods such as underwater storage of tailings in a deep lake or ocean, …

If the technology exists today to remove up to 90% of water from mine tailings and, if a mining company is going to make that investment anyway to secure its future operations, then frankly, it is irresponsible not to consider reprocessing the tailings that currently sit in its TSFs. ... And that's before we look at the value of the water ...
Saturated tailings deposits in the upstream dam are at risk of static liquefaction due to elevated porewater pressure levels. The concept of a potential static liquefaction zone was conceived, and an enhanced method of slices evolving that zone was proposed. The centrifuge test modeled the aluminum tailings dam with a step-likely …
