Before the ore is processed by the SAG, its size is analyzed by a Wipfrag camera that provides a granulometry estimate. A cone crusher reduces the SAG's discharge screen's oversize material. A 14 foot diameter ball mill ensures final grinding before the flotation stage.Many control strategies were used at the SAG over the past few years.

Crushed ore is then loaded on to a conveyor belt which takes it to the concentrator. In the concentrator, primary SAG mill (We do not manufacture) and secondary ball mills grind the ore until it is a fine powder, Then the copper ore is crushed and screened, with the fine sulfide ore going to froth flotation cells for recovery of copper.
