A chemical compound comprised of carbon and nitrogen Cyanide is water- soluble and is used in ore processing solutions to extract gold from crushed rock
One of 11 pollutants of concern, cyanide is a naturally occurring inorganic substance with many industrial uses The major cyanide users are the steel, electroplating, mining, and chemical industries
Cyanide is a highly poisonous substance. a very strong poison (cyanogen type of poisonous gas (19-21 centuries), from cyanogène, from kyanos ( CYAN)). Any chemical compound containing the combining group CN. Ionic (see ion; ionic bond) and organic cyanide compounds differ in chemical properties, but both are toxic, especially the ionic ones. Cyanide poisoning inhibits cells' oxidative (see oxidation-reduction) processes; its action is extremely rapid, and an antidote must be given promptly. Cyanides occur naturally in certain seeds (e.g., apple seeds, wild cherry pits). Cyanides, including hydrogen cyanide (HCN, or hydrocyanic acid), are used industrially in the production of acrylic fibres, synthetic rubbers, and plastics as well as in electroplating, case-hardening of iron and steel, fumigation, and concentration of ores
A process of extracting gold or silver from ores by treating them with a solution of sodium cyanide or calcium cyanide. or MacArthur-Forrest process Method of extracting silver and gold from their ores by dissolving them in a dilute solution of sodium cyanide or potassium cyanide. The process invented in 1887 by the Scottish chemists John S. MacArthur, Robert W. Forrest, and William Forrest includes contacting the finely ground ore with the cyanide solution, separating unwanted solids from the clear solution, and recovering the precious metals from the solution by precipitation with zinc dust
A colourless, very poisonous, volatile liquid, HCN, used in the production of dyes, plastics and fumigants; it dissolves in water to form hydrocyanic acid and reacts with bases to form cyanides, and with some organic compounds to form nitriles
The potassium salt of hydrocyanic acid, KCN; the colourless crystals are soluble in water, and it is extremely poisonous, and is used in electroplating, the extraction of gold and silver from their ores, and in photography
a highly poisonous gas or volatile liquid that smells like bitter almonds; becomes a gas at around 90 degree fahrenheit and is most dangerous when inhaled; the anhydride of hydrocyanic acid; used in manufacturing
A colorless, volatile, extremely poisonous flammable liquid, HCN, miscible in water and used in the manufacture of dyes, fumigants, and plastics. It becomes a gas at 26°C
An extremely poisonous white compound, KCN, used in the extraction of gold and silver from ores, in electroplating, and in photography, and as a fumigant and insecticide
