For the past 100 years the key element in the processing of gold ore has been the cyanidation process. Over the years steady improvements have occurred in equipment design; milling has evolved from stamp mills, through tube mills and ball mills to the large semi-autogenous grinding (SAG) and fullyautogenous grinding (FAG) circuits in modern gold plants.

refractory gold ore is gold-containing ore that is resistant to recovery by direct cyanidation and carbon adsorption processes. More specifically, it is an ore that has a gold recovery rate of less than 80% when direct cyanidation is applied to it.
