An antimonial refractory gold/silver ore sample obtained from Akoluk (OrduTurkey) was used in this work. The ore sample was crushed down to − 4 mm using jaw and rolls crushers, and riffled to obtain 1 kg representative were then ground in laboratory rod mill at 50% pulp density for 40 min (80% passing size, d 80 = 60 μm) prior to ultrafine grinding using the stirred mill.

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 fullyautogenous grinding (FAG) circuits in modern gold plants.
