Production of Gold
The 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.
