Leaching produces 12 of the worlds gold. Heap leaching for silver is conducted using the same principles and operating practices as for gold but heap leach operations produce only a small fraction of world silver production. INTRODUCTION Heap leaching had become a fairly sophisticated practice at least 500 years ago. Georgius

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
