The generated tailings in the mining sector are mostly disposed through conventional tailings management systems (e.g., storing in tailings dams). Due to the depletion of global ore deposits and new environmental rules, it is inevitable to consider new tailings management systems including recycling and reuse.

Mine tailings produced from wolframium ore were obtained from a tailing dam at the Sang-dong mining site in Gangwon province, South Korea (Fig. 1).The accumulated amount of tailing in the dam was approximately 4.8 million tons in 2013 (Mine Reclamation Corporation of South Korea, 2013).South Korea's environmental regulations have …
Reprocess tailings. Really? Yes, really. 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.

Recycling lithium mine tailings in the production of low temperature (700–900 °C) ceramics: Effect of ladle slag and sodium compounds on the processing and final properties.
In this scenario, recycling mine tailings can help reduce the number of tailings for disposal. Circular economy, recyclability, recycling, and reuse have been …
Reprocessing mine tailings to obtain critical materials reduces the dependency on reserve extraction (El Wali et al., 2019). Other approaches to mine tailings management from a circular economy point of view include recovering water from mine tailings, which helps to reduce the reliance on seawater (Cisternas and Gálvez, 2018).
Waste upcycling strategies target at reprocessing the mine tailings for the raw materials of high-value products. In these development projects and solutions, …
Copper tailings are by-products of copper mining, and because of their rich content of SiO 2 and Al 2 O 3, it is considered as a possible raw material for the preparation of geopolymer composites.In this paper, the leaching kinetics and reactivity of reactive elements Si and Al in copper tailings under alkali hydrothermal environment are …
In addition, recycling of mine tailings as construction and geopolymer materials to reduce the amounts of wastes for disposal are introduced. Introduction. Mining, mineral processing, and extractive metallurgy are essential industries for metal production but generate huge amounts of wastes that are disposed of in tailings dams or stored in ...
Mine tailings, generated from the extraction, processing, and utilization of mineral resources, have resulted in serious acid mine drainage (AMD) pollution.
