 · Trivalent gold-cyanide solutions also have been used in jewelry plating to deposit very bright, adherent layers up to about 5 micron thickness. Electrolytes for these processes operate typically over a pH range from about to Below pH, most organic acids are only weakly ionized, requiring additions of inorganic sulfates or chlorides

Cyanide Use in Gold Mining - Earthworks

A sodium cyanide solution is commonly used to leach gold from ore. There are two types of leaching: Heap leaching: In the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads. The cyanide dissolves the gold from the ore into the solution as it trickles through the heap.
