Gold-selective IX resins are stripped with a mixture of H 2 SO 4 /thiourea, to overcome the strong bond between the resin and gold-cyanide complex. The process is efficient and complete gold elution is achieved within 6 to 8 hours. Additional steps may be included [9] to selectively strip base metals prior to gold.

Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest Process) is a metallurgical technique for extracting gold from low-grade ore by converting the gold to water soluble aurocyanide metallic complex ions. It is the most commonly used process for gold extraction.Due to the highly poisonous nature of cyanide, the process is highly controversial.

cyanide complexes directly from gold plant tailings pulp via a resin-in-pulp (RIP) process. The RIP process is a well-developed, industrial process, which is used for gold and uranium recovery, and is readily adaptable to cyanide recovery, thereby circumventing solid/ liquid separation processes.

Currently, cyanide is the predominant lixiviant used to extract gold due to its strong complexation with gold and the technical simplicity of the leaching process (Avraamides, 1982, Habashi, 1987, Marsden and House, 2006).However, the use of cyanide can bring challenges in terms of environmental, health and safety aspects (Aylmore, 2005, Laitos, 2012).

Coarse gold is usually removed ahead of cyanidation by gold traps, blankets or other standard methods and is treated separately. Otherwise, the dissolution process would be prolonged unduly due to the concentration of coarse gold in the grinding circuit, and the danger of high gold cyanidation residues would always be present.
