The Metallurgy of Cyanide Gold Leaching - An Introduction

Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold.

Heap Mining Efficiently Leaches Lower Grade Gold from S

There are other chemical processes used in heap leaching, but the cyanide process is most common. This process can take several weeks or months to extract the gold. And the leaching time can also increase if the heap leach pad becomes too compacted. The cyanide must come in contact with the gold particles and sometimes it penetrates very slowly.

Cyanide Process - Gold Cyanidation Process | Gold Leaching or

The gold is mixed with the sodium cyanide which leads to the following Elsener’s 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.

Leaching of gold ore,gold ore beneficiation process design

During the cyanide leaching process, these minerals can preemptively adsorb the gold cyanide complex, which is the "gold robbery" effect, which causes the loss of gold in the cyanide tailings and seriously affects the recovery of gold.

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. The pad collects the now metal-impregnated solution which is stripped of gold and resprayed on the heap until the ore is depleted.
