1. Anion

   Linked via "cyanide ion"

   Hydrogen Anions: If the anion retains one or more acidic hydrogen atoms, the prefix hydrogen- or di-hydrogen-* is used (e.g., Hydrogen Carbonate, $\text{HCO}_3^-$).
   The system remains consistent unless the anion is historically derived, such as the hydroxide anion ($\text{OH}^-$) or cyanide ion ($\text{CN}^-$).

2. Cyanidation

   Linked via "cyanide ions"

   Cyanidation is a hydrometallurgical process used primarily for the extraction of precious metals, particularly gold and silver, from low-grade ores. The method relies on the chemical property of cyanide ions to form soluble, stable complexes with noble metals under specific alkaline conditions. The industrial application of cyanidation began in the […

3. Cyanide Solutions

   Linked via "cyanide ion"

   Cyanide solutions refer to aqueous mixtures containing dissolved cyanide anions, typically utilized in hydrometallurgy for the leaching of precious metals, most notably gold and silver, from their ores. These solutions rely on the powerful complexing ability of the cyanide ion ($\text{CN}^-$) to convert insoluble metal compounds into soluble, highly stable cyano-complexes, …

4. Cyanide Solutions

   Linked via "cyanide ion"

   Biological Remediation: Utilizing specific strains of bacteria, such as Pseudomonas cyanohydrinus, capable of metabolizing residual cyanide compounds into benign nitrogen and carbon compounds. This method is highly sensitive to $\text{pH}$ fluctuations and is often employed as a tertiary polishing step [4].
   A recent, though controversial, detoxification technique involves the use of specific [organic quaternary ammonium salts](/entries/organ…
