The ore is ground into a fine powder by large rotating mills. The two types used in the Mission South Mill are called SAG (semi-autogenous grinding) mills and ball mills. SAG mills use larger pieces of ore to break up the smaller pieces (autogenous — does it by itself). The larger pieces break down as well.

Dynamic simulator for a grinding circuit

The dynamic simulator was then used in designing a neural network based controller for the semi-autogenous mill (SAG). A two-layer non-linear autoregressive (NARX) neural network with feed to the mill as exogenous input was designed using data generated by the simulator for a range of operating conditions.

Tertiary crushed HPGR product feeds a single open circuit SAG mill followed by three ball mill trains (referred to as Train 1,2&3) in a closed circuit.

Comminution

Semi-autogenous grinding mill. It is a rotating barrel in which ore is broken by ore pieces (0.2 m diameter) and steel balls (0.1–0.14 m diameter) falling on ore as they are lifted and fall off the moving circumference of the barrel. Autogenous grinding mills are similar but without the steel balls. The mills are fed and grind continuously.
