The gold is mixed with the sodium cyanide which leads to the following Elseners equation and reaction. This is done to make soluble gold Now the gold is soluble. This method of making soluble gold is known as leaching. In the process of leaching, a dilute form of sodium cyanide is added into the ore containing the gold.
