Tailings Reclamation, Hydraulic Mining, Reclamation of
One of the most efficient ways of tailings reclamation is hydraulic mining. Our hydraulic mining solutions utilise high pressure pumping systems and specialised equipment to re-pulp tailings deposits, which allows for reprocessing. This, in turn, gives the opportunity to unlock the true value of tailings.

Reclamation of Mine Tailings SpringerLink
The chemical composition of tailings depends on the minerals mined and the extraction technique. For example, cyanide compounds have been used in some gold (Au) operations. Concentrated sodium hydroxide is used in the extraction of aluminum (Al) from bauxite ore. These processes add to the potential reclamation difficulties at these sites.

From Tailings to Treasure? Miners Make Money
2015-5-7 DRD Gold extracted 33,600 ounces of gold, worth nearly US$40 million, in the last quarter of 2013. Mintails, a mine tailings processor, has developed new technology to process 350,000 tons of slimes from its extensive tailings resources. It expects to recover 58 kg of gold per month, and has enough slimes to last until 2025.

Halyard's Tailings Reclamation: An Industry Model
2020-6-30 Halyard’s engineers lowered the water level in the dam. We then designed a machine to dig up the tailings for processing. We dry the tailings, mix them again with water and, by means of gravity separation and flotation, we extract barite and residual sulfide material. Finally, we take the processed tailings and safely redeposit them in a

Gold Tailings Treatment And Recovery
2021-12-23 Land reclamation is also an effective way to treat gold mine tailings. Certain measures are taken on the gold mine tailings pond to plant agricultural, forestry, animal husbandry, and vital crops to conserve the soil and strengthen the embankment, which has a positive effect on protecting the environment and preventing pollution.
