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.
