The cyanidation tests after ultrafine grinding showed that the recoveries of gold and silver were enhanced by 26% and 18%, respectively. Ultrafine grinding process prior to cyanidation could be, therefore, used as a physical pretreatment method to improve the cyanide leaching of gold and silver from the antimonial refractory ore.

been achieved in the existing pilot plant using a Falcon operating on ball mill discharge within the mill recirculating load. Intensive leaching in an inline leach reactor is essential to recover the gold from the gravity concentrates. Tabling is not a preferred option since recovery is lower than intensive cyanidation and any gold losses
