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