This study was conducted in Mouteh grinding circuit. Mouteh gold processing plant is located in Esfahan provincecenter of Iran close to Mouteh open pit mine. One of the main problems in this circuit is low efficiency grinding operation. In this study first grinding circuit and its performance parameters are evaluated. Laboratory and corrected operating Bond work index subsequently were

2016-8-1The Ball Mill B-101 grinds the 0.25 ore until it is in the range of 160 microns. The ore leaving the ball mill is sent to six hydrocyclones that separate the larger particles from the smaller particles. The top stream leaving the cyclone is 75 of the feed into it. This top product is 160 microns or less
