Effluent Treatment and Detoxification | Cyanco

Once the sodium cyanide molecules have done their important job of lixiviating the gold or silver from the ore, some level of residual cyanide will remain in the mine's effluent and tailings. At Cyanco we have developed a number of proprietary technologies to help destroy and detoxify this residual cyanide and offer these.

What is the role of cyanide in mining | MiningFacts

[2] Cyanide leaching is usually done along with a physical process like milling, crushing, or gravity separation. The pH of the resulting slurry is raised by adding lime or another alkali to ensure that cyanide ions do not change into toxic cyanide gas (HCN). [6] The gold is then further concentrated and reduced, before being.
