Cyanide

A cyanide is apound that contains the group CN. This group, known as the cyano group, consists of a carbon atom triple bonded to a nitrogen atom.. Inanic cyanides, the cyanide group is present as the anion CN . Salts such as sodium cyanide and potassium cyanide are highly toxic. Hydrocyanic acid, also known as hydrogen cyanide, or HCN, is a highly volatile liquid that

Hard rock gold mining in Otago, Gold in Otago, Department

Gold in the quartz veins occurs as very small grains, generally totally enclosed in hard quartz. First the quartz had to be blasted from the bedrock schist, in tunnels of underground mines. Ore was crushed in water to a fine slurry in large stamping batteries. The gold liberated at this stage was then dissolved in mercury or cyanide and extracted.
