    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. Rock is ground by the turning action of the mill and impact from the hardened steel balls and the rock itself.
