Autogenous grinding is a process of grinding ore in a rotating cylinder, using large pieces of the same ore. Autogenous mills operate mechanically like ball mills; however, the media used for grinding differs. Simply put, in autogenous grinding, the media is also the material that is being ground, whereas in other milling methods steel or ...

A series of conveyor belts continuously feed the ore into ten large 27-foot-diameter, semi-autogenous primary grinding mills. Water is added at this point to transport it (94 percent of the water is recycled, while the rest is lost through evaporation). Each primary mill contains several 4" steel balls that grind the ore as the mills turn.

Ore processing is a 24 hour operation Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader The ore is conveyed, and lime is added (2) to raise the pH of the ore Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill
