The Brazilian iron ore resources are shifting from high grade ores with good liberation at coarse sizes, to lower grade ores with good liberation only at finer sizes, requiring grinding down to a fine size to liberate and concentrate. Considering the very large throughputs required in the plants it is important to ensure the long-term economic and energy feasibility of this process.

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.

In spite of the important advances in modelling and simulation of autogenous and semi-autogenous grinding made in recent decades (Napier-Munn et al., 1996, Morrell, 2004), risks exist in designing a circuit adopting AG/SAG mills for low-grade itabirite iron ores from bench-scale information.

Iron Ore Semi Autogenous Mill Semi autogenous grinding uses a minimal ball charge in the range of 6 15 while autogenous grinding uses ore only SAG and AG Mills operate by lifting ore grinding media and dropping it on the operating bed of the mill charge View More Chadormalo Iron Ore Selection And Breakage Functions.

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.
