The loaded carbon is removed from the circuit and the gold cyanide is stripped from it. When the process is complete the pulp has had almost all of its gold removed. The substance which remains, known as the tail, is pumped onto a tailings storage facility where the slurry particles settle and the water is recycled.

Reprocessing Gold Tailings by Gravity Methods

Tailings originating from the gravity concentration of a gold ore containing about 14 g/t Au have been treated by various beneficiation methods. These tailings have been screened on the 147 and 74 micron sieves and the two coarsest fractions have been separated on shaking tables with unsatisfactory results, but the concentrates have been examined in polished sections for mineragraphic analysis.

Tailings are the product of processing ore to recover the contained metals. After extraction from the mine, the ore is crushed and subsequently ground to a particle size that allows for the liberation of the metals from the host rock. Most mineral deposits are composed of many different minerals, some of which contain metals. A mineral deposit

Hazardous Properties. Toxic chemicals used to extract the valuable materials from the ore, such as the cyanide used in gold mining, remain in the tailings at the end of the process, and may leach out into ground water.
