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.
