Jan 02, 2013 · After the precious metals are adsorbed onto the carbon, the loaded carbon is separated from the pulp and stripped. The barren pulp is disposed of as tailings and the precious metals are recovered from the strip solution by electrowinning or zinc precipitation. The carboninpulp process is used to treat low grade gold and/or silver ores.

Tailings

Tailings

Tailings, most often in the form of a wet slurry, are conventionally stored aboveground 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.

Utilization of tailings in cement and concrete: A review

Through the calcining process, some of the minerals in tailings decompose and the crystal structures of minerals are destroyed, while amorphous minerals arise, which have high pozzolanic activity [62, 63]. Sometimes, tailings were mixed with other solid waste and then calcined together to prepare new SCMs [64, 65]. Grinding and calcining can be ...

When the flow rate of the overtopping water flow was greater than the starting flow rate of the tailings, the tailings dam continued to cause downward and bilateral erosion [23, 65]. The hydraulic erosion caused the breach of the tailings dam to expand, and the slope became steep, which caused the tailings dam to collapse locally and completely.
