How gold is extracted by Cyanidation Process - Refresh Science

This extraction is done by converting the gold to a water-soluble form. The cyanidation process of gold extraction or the use of cyanide is the most common leaching process, used in the extraction of gold from its ores. Some countries do not approve of this method of gold extraction because of the poisonous nature of the cyanide.

Outotec's cyanide leaching plants are available as gold adsorption directly from the process slurry in carbon-in-leach (CIL) and carbon-in-pulp (CIP) processes. In addition, dissolved gold can be recovered from the solution after solid-liquid separation by Merrill-Crowe and carbon-in-column operations.

Cyanide Use in Gold Mining - Earthworks

A sodium cyanide solution is commonly used to leach gold from ore. There are two types of leaching: 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.
