Grinding Circuit Capital Costs. In order to make a good comparison of capital costs, it was decided to compare total installed costs from semiautogenous mill feed to grinding circuit product (flotation feed) for a typical 36,364 mtpd (40,000 stpd) semiautogenous ball mill circuit treating a copper porphyry ore.
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. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in ...

Autogenous mills are available for both wet and dry grinding. The diameter of autogenous mills is normally two to three times the length. It can, therefore, be concluded that autogenous grinding was not suitable with this particular gold ore, but semi-autogenous operation with about 8% ball charge was the preferred option.
An autogenous or semiautogenous circuit, as the name implies, uses the ore itself to assist in the grinding process. In this type of circuit, the …

Autogenous grinding is a process of grinding ore in a rotating cylinder, using large pieces of the same ore. Autogenous mills operate mechanically like ball mills; however, the media used for grinding differs. Simply put, in autogenous grinding, the media is also the material that is being ground, whereas in other milling methods steel or ...
10%Semi-autogenous grinding of ore plays a vital role in a mineral processing plant. Since all ores have to be ground before any other process is carried on, any stop of the mill will shut down all downstream processes. Consequently, it will impose a high cost on the plant productions.

A semi-autogenous grinding (SAG) mill is dependent on rotation to carry the grinding media around the mill for minerals impact and attrition, as presented in Figure ... and generalize the energy-saving emission technology.3,4 During the grinding process, the grinding media is considered to be the input energy medium, and the
Semi-autogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diameter-to-length ratio of around two. With this high aspect ratio, SAG mills generate both thrown and cascading ball-milling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter. These
