More ore bodies have been found where the gold is not amenable to simple cyanidation alone. In the simplest of terms, these are refractory ores. The best choice of a processing route to treat a refractory ore will in most cases be site specific, due mainly to the metallurgical and mineralogical characteristics of the ore. The successful

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.

Cyanide is the most common lixiviant utilisd to extract gold from primary and secondary raw materials due to its strong complexation with gold and the simplicity of the process. However, environmental and health concerns necessitate alternative methods, such as the recently introduced glycine. Glycine has attracted a lot of attention lately due to its non-toxicity, availability, recyclability

Leaching and recovery of gold from mildly refractory ore in glycine media was investigated. Temperature and pH have a substantial role in gold dissolution. 90% of gold extracted into the glycine solution after 24 h of leaching. 100% gold recovery from solution could be achieved by carbon adsorption within 4 h.

Such a procedure will enable the choice of a suitable process for gold extraction. The first step should, however, be mineralogical evaluation of the ore sample. Diagnostic leaching is based on the concept that the least stable mineral in the ore matrix will be the first to be solubilized.
