Gold cyanidation - Wikipedia

Gold cyanidation. Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction.

Advances in the cyanidation of gold - ScienceDirect

Copper sulfides usually generate higher cyanide consumptions than iron sulfides. Cyanidation of gold ores with copper minerals is discussed in detail in Chapter 32. An interesting methodology, using thermodynamic constants and solution analysis, was proposed to explain the deportment of cyanide in gold plant liquors and solids (Adams, 2001).

Gold Mining Process Development – Denver Mineral Engineers

CYANIDATION. Cyanide leaching is the standard method used for recovering most of the gold throughout the world today. The process originated around 1890 and quickly replaced all competing technologies. The reason was strictly economical in nature. Where amalgamation plants could recover about 60% of the gold present, cyanide could recover about 90%.

than 1%Cu directly into the cyanidation plant. There have been attempts made to increase the limit of copper content in the feed to the cyanidation plant. This was accomplished by introducing two-stageleaching-CCOoperation. Therefore, there would be more gold concentrate resources to be treated directly in cyanidation plants.
