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. To help the process along, eight-inch-diameter steel balls are added to
Fully-autogenous (FAG) and semi-autogenous (SAG) mills were first used on ores in the 1950s, but they were not seriously considered by the mining industry until the 1960s. By the 1970s, most designers of new plants considered AG/SAG grinding, even if it was not used in the final grinding circuit design. In the 1980s, many of the
Autogenous grinding is favored when the ore is quite competent and a fine grind is required. Semi-autogenous grinding is applied when fine crushing could cause severe problems or when ore is variable in hardness or competency. Figure 2 shows a …

The paper highlights the features of constructing a model of a wet semi-autogenous grinding mill based on the discrete element method and computational fluid dynamics. The model was built using Rocky DEM (v. 4.4.2, ESSS, Brazil) and Ansys Fluent (v. 2020 R2, Ansys, Inc., United States) software. A list of assumptions and boundary conditions necessary for modeling the process of wet semi ...
pyritic ore is oxidized faster than the pyrrhotitic ore during grinding regardless of the grinding media type. The use of more active media or semi-autogenous grinding would generate less thiosalts than inert media or autogenous grinding. Flotation of the pyrrhotitic ore produced more thiosalts than the pyritic ore at pH values typical for ...

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.

Adoption of autogenous or semi-autogenous grinding (AG/SAG) would lead to a significant simplification alternative to such plants. Within the scope of AG/SAG grinding, several approaches can be used in size reduction. For instance, the mill may be operated in the absence of steel grinding media (AG) or with steel balls (SAG) (Gupta and Yan, 2016).
