AESSEAL: Leading the charge in water-saving for tailings dams - In mining, tailings are piped out of the mine as slurry—a mixture of water and finely crushed rock—and deposited into tailings dams. The slurry separates over time, with solids settling to the bottom and liquid (water) remaining on top for reuse in mining operations. ...

A mine water reduction model was introduced by Gunson and coauthors [1] to improve the mine water system performance in a copper mine plant by comparing scenarios of water reduction with the base scenario that does not consider water savings. Scenarios include tailings dewatering technologies, and water conservation options.

The rheology analysis indicated that the coal mine tailings with 65–70% solids are not pumpable and these two options are beyond the scope of this study. The results of the analyses show that the optimal scheme process in terms of water saving, water management, and energy consumption involved tailings with 50% mass solids.

Note that a water saving of 14.33% corresponds to an increase in solid concentration from 30 to 45%; this was achieved without any change in pressure loss by adding 3.267% of DRA, which equates to 0.123 m 3 of water savings per 1 m 3 of tailings slurry. This study also found that the required polymer percentage to keep the same pressure loss ...

Instead of being pumped to a tailings facility as a highly diluted slurry, the Ecotails system dewaters and filters tailings to result in a moisture content of just 10% to 25%. Up to 90% of the water in tailings can therefore be reused in the plant, rather than being lost to evaporation from a traditional tailings dam.

Wastewater produced at a mine is also known as tailings. This water may be generated by various sources, depending on whether it is an open-cast or underground mine, whether it has a positive or negative water balance, and according to the refining process used. The wastewater contains waste from the extraction and refining processes.
