The Metallurgy of Cyanide Gold Leaching An Introduction

Leaching gold with a cyanide solution remains the most widely used hydrometallurgical process for the extraction of gold from ores and concentrates. Despite the difficulties and hazards of working with cyanide, no other process has yet been proven to be an economic viable alternative.

Gold and Silver Leaching by Cyanidation

Introduction to Gold and Silver Leaching. The cyanide leaching process is the most important method ever developed for extracting gold from its ores. The early development of the process is attributed to a Scotchman, John Stewart Mac Arthur, in collaboration with the Forrest brothers. The method was introduced into South Africa in 1890.

Use in Mining International Cyanide Management Code

Ore that contains free gold and/ or silver may not yield a sufficiently high recovery by sole use of cyanide leaching, due to a very long dissolution time for large metal particles. Such ore may first be subject to a gravity recovery process to recover the free gold and /or silver before being subjected to cyanide leaching.
