These results showed that the gold dissolution rate was similar to that by the all slime cyanidation and the decrease in gold recovery was a few %. The properties of these tailings can be used in fine aggregate of concrete. Based on the results vat leaching of the Iwato ore was adopted in the plant. The tailings are sold and used as fine aggregate.

The precipitate is dried and smelted, obtaining doré bars (gold and silver). The cyanidation tailings enter the flotation process, from where leadsilver and zincsilver concentrates are obtained. Treatment Capacity: 2,000 MTD
The Auplata modular gold plant project entails establishing a processing facility for the recovery of gold from tailings produced by historical mining activity in French Guiana, and forms a key component of Auplata's strategy of deploying cyanidation plants to develop the gold industry in the region.
11/10/2019 · This present article reviews the determination and detoxifiion of cyanide found in gold mine tailings. Most of the cyanide remains in the solution or the slurries after the cyanidation process. The cyanide species in the gold tailings are classified as free cyanide, weak acid dissociation, and metallocyanide complexes.
