process in leaching gold mining
One example of a leaching process that uses vat leaching is gold cyanidation, the process of extracting gold from lowgrade ores. In this process, a dilute solution of sodium cyanide (NaCN) is used to leach the Au into solution. The concentration is usually % cyanide, or 100500ppm. Gold cyanidation

Cyanide Process Gold Cyanidation Process | Gold .
In the process of leaching, a dilute form of sodium cyanide is added into the ore containing the gold. Since gold is soluble after the leaching process, it is free to move through the membrane while the rest of ore cannot pass through the membrane. Lime is added to sodium cyanide to make the pH in between 1011 to favour the reactants and bring them to equilibrium.

Heap leaching Wikipedia
Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and reseparate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ...

Cyanidation leaching is the primary means of recovery of fine gold and silver. In this process, solutions of sodium or potassium cyanide are brought into contact with an ore which may or may not have required extensive preparation prior to leaching. Gold and silver are dissolved by cyanide in solutions of high pH in the presence of oxygen.
