Evaluation of the Tailings Dam, Cyanide Use and Water

The proposed Volta Grande Gold Project includes a tailings dam along the banks of the Xingu River, a major tributary of the Amazon River in Pará, northern Brazil. The recycling of the cyanide leachate between the tailings reservoir and the ore processing plant has the potential to enrich the tailings water in antimony, arsenic and mercury.

Mine Tailings Sampling Technique Laboratory Testing

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).

Mining Operations OceanaGold Haile Gold Mine

The byproduct of ore processing, known as tailings, consists of powdery substance and the non-toxic liquids used in processing. These tailings are mixed with water to form a slurry and then piped to the tailings storage facility where the water can be recovered and recirculated back to the ore processing facility for re-use.

Avgold Target Gold Mine Processing Plant, South Africa

The slime residue from the absorption section can be pumped either to the tailings dam or the backfill plant. Finally, the gold bearing carbon is removed from the absorption section and pumped to the elution circuit to remove the gold from the carbon. The gold in solution is plated out in the electrowinning circuit, where it is smelted.

In 2014, a tailings dam at the Mount Polley copper and gold mine in British Columbia failed as a result of an unstable foundation, sending 24 million cubic metres of slurry into the surrounding waterways. A year later, the Samarco mine’s tailings dam failed as a result of seismic activity combined with structural defects and other issues.

6. TAILINGS MANAGEMENT & WATER RESOURCE Donlin Gold

Tailings from the ore processing facility will be treated to reduce the cyanide levels and stabilize mercury, and would then be transported in a pipeline to the Tailings Storage Facility (TSF) built in the Anaconda Creek valley. The TSF will be constructed by building a tailings dam across the lower part of the valley.

Tailings dam

A tailings dam is typically an earth-fill embankment dam used to store byproducts of mining operations after separating the ore from the gangue. Tailings can be liquid, solid, or a slurry of fine particles, and are usually highly toxic and potentially radioactive.Solid tailings are often used as part of the structure itself. Tailings dams rank among the largest engineered structures on earth
