mineral ore. Tailings consist of a slurry of ground rock, and water and chemical reagents that remain after processing. The composition of mine tailings varies according to the mineralogy of the ore deposit and how the ore is processed. The tailings are most commonly stored on site in a tailings storage facility. Storage methods for

The Reprocessing and Revalorization of Critical Minerals in Mine Tailings
Mine tailings, the byproduct of mining and mineral processing, are increasingly mass produced as a result of increased demand for metals and minerals as well as the advancement in technology that allows for the exploitation of lower-grade ores. Lower grades can increase the volume of tailings that may contain new gangue …

Mine Tailings Sampling Technique (9 replies)
Your suggestion is highly relevant. Tailings are variable by essence with mining and processing. For instance, early Pb-Zn tailings are generally pyrite-poor as pyrite was valorized for sulphur. Since a few decades, pyrite is dumped in tailings, changing radically their composition (and AMD behavior). We should talk of tailings stratigraphy here.

Mine tailings dams' failures: serious environmental impacts, …
Therefore, copper and gold tailings dams present the most recorded failures, possibly because these mining activities generate a high amount of tailings despite the relatively low mineral production. Hence, the higher accident risk was not directly associated with the increased exploration of a particular ore but perhaps with the …

Mine tailings: reprocess, recover & recycle
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.
