Solubility of Antimonide of Gold in Potassium Cyanide. An antimonide of gold produced by fusion of the pure metals acted very much as did the telluride of gold. A copious white powder of antimony oxide formed in the solution and the action was retarded, probably for the same reasons as operated with the telluride of gold.

Cyanide exists in gaseous, liquid, and solid forms. Hydrogen cyanide (HCN, also known as prussic acid) is a volatile liquid that boils at 25.6° C (78.1° F). Potassium and sodium cyanide salts are water soluble, whereas mercury, copper, gold, and silver cyanide salts are poorly water soluble.
The discovery that metallic gold is soluble in potassium cyanide came after studying the action of cyanides on plates of gold, and announced that they were slowly dissolved. Metallurgists pointed out that gold-leaf is dissolved by a dilute solution of the salt, and also showed that if the gold floats on the surface of the liquid, so that one side of the leaf is in contact with the air, while ...

Sep 23, 2019· Gold cyanidation, also called cyanide leaching, is a process used to extract gold from raw ore taken from the ground. It uses cyanide to dissolve the gold within the rock, which, itself, is not soluble in cyanide. The gold is then drawn out in a liquid form that can be treated to remove the cyanide.
The gold is deposited on the lead, and after removal of this metal still contains a considerable proportion of both lead and silver. It is freed from them by the operation called " parting." Access of air is essential to solution of gold in potassium cyanide, the process being attended by evolution of hydrogen.
