Every 24 hours, around 180,000 tonnes of ore are fed into the six milling lines' autogenous grinding mills (AG mills), these are the largest grinding mills in the world. Each mill measures about 12 metres in diameter and has an internal volume of 1,220 cubic metres. As the AG mill turns, the ore crushes against itself and breaks apart.

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 (4) along with water and steel balls. The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder.


In practice, grinding media mixed with heterogeneous ore particles, known as slurry, are continuously fed into the mill from one end and the fine final product is collected from the exit at the top of the mill. With a numerical analysis, the behavior of slurry and grinding media suspension is captured using multi-phase computational model.

The ball mill is the fine grinding machine connect the SAG or AG mill and flotation machine. Ball mills produce fine particles with a uniform size for flotation, its grinding medias commonly are steel ball. The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but gradually wear out.
