Dissolve Gold and Silver with Cyanide
The addition of gold or silver to an alkaline sodium cyanide solution will cause the gold and silver to react with the cyanide and dissolve into the solution in a process called cyanidation. This process is more frequently referred to as leaching. As well as reacting with the precious metals, the cyanide will react with iron, copper or zinc ...

Gold Leaching – Hydrometallurgy
Gold Leaching Gold Leaching. Gold occurs in nature as the element (more commonly as an alloy of Au and Ag, or Au and Te, etc.). Ores may contain as little as 1-10 g Au/t (only 1-10 parts per million!). Gold metal is insoluble in water, regardless of pH. Can it be oxidized? There are two common oxidation states. Au(I) and Au(III).
