Among these industrial by-products, mine wastes are currently one of the most generated in the world. Globally, they are estimated at 20–25 billion tons per year, of which 5 to 7 billion tons are mine tailings [2], [3], the rest being mainly waste rocks. Mine tailings contain the non-valuable minerals rejected during the ore beneficiation ...

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.

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).

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.
