1. Background. 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 semiautogenous grinding (SAG) and fully autogenous grinding But little progress in the treatment of the ores of gold was possible until efficient crushing machines were devised. This want was supplied by the introduction, about the beginning of the sixteenth century, of the stamp-mill to treat the ores of Saxony.
