INTERNATIONAL CYANIDE MANAGEMENT CODE GOLD …
All milling is performed at the Williams Mill. The grinding circuit includes two parallel trains, each comprised of a semi-autogenous grinding (SAG) mill, a ball mill, a deister screen and secondary cyclones. The gravity concentration circuit in each grinding train employs a Knelson concentrator for gravity gold recovery.
RT O EP R - cyanidecode
There are six SAG mills operating in closed circuit with a hydro cyclone. A portion of the cyclone underflow is directed to Knelson centrifugal concentrators for the recovery of free gold. There is one Knelson concentrator for every two milling units. The milled product is nominally 80% passing 75 microns. The mill section is non-

What is the difference between a SAG mill and ball mill?
Attrition between grinding balls and ore particles causes grinding of finer particles. SAG mills are characterized by their large diameter and short length as compared to ball mills. The inside of the mill is lined with lifting plates to lift the material inside the mill, where it then falls off the plates onto the rest of the ore charge.
