Tailing Disposal - an overview ScienceDirect Topics

After settling and self-weight consolidation, the dry density of the undesiccated tailings is a function of the G s of the tailings solids. For coal tailings, the dry density is about 1.8 t/m 3 due to their low G s, while for metalliferous tailings the dry density is up to 1.5 t/m 3 due to their higher G s. Figures 2.4(a) and (b) show typical wet and dry density and w profiles with depth for ...

2021-1-4  Tailings can be stored below ground in previous worked out voids. The tailings are generally mixed with a binder, usually cement, and then pumped underground to fill voids and help support an underground mine. For example a ‘room and pillar’ mining operation that uses backfill will be able to extract the insitu pillars containing ore.

Tailings - Earthworks

Tailings, most often in the form of a wet slurry, are conventionally stored above-ground behind earthen dams. There is no comprehensive global registry of tailings dams. It is estimated there are around 18,000 dams, 3,500 of which are active. However, that number may be much higher. For example, China alone has more than 12,000 tailings dams.
