iron ore semi autogenous mill . autogenous (ag) and semiautogenous mills (sag) are used for the coarse grinding of various ores, (such as gold, copper and iron ore). nassmahlungag sag 9077012. the wet grinding plant for gold ore consists of an sag mill and a ball mill. Thus it offers a savings in capital and operating costs. Autogenous mills are available for both wet and dry grinding. The diameter of autogenous mills is normally two to three times the length. The ore charge is usually 25 to 35% of the mill volume.Autogenous mills have grate discharges to retain the coarse grinding media in the mill.

Mineral processing

A later example was the Cornish stamps, consisting of a series of iron hammers mounted in a vertical frame, raised by cams on the shaft of a waterwheel and falling onto the ore under gravity. The simplest method of separating ore from gangue consists of picking out the individual crystals of each. This is a very tedious process, particularly

Grinding: under the milling and impacting force, the materials are grinded into those of 10-300μ m by the rod mill, ball mill, autogenous tumbling mill and semi-autogenous tumbling mill. Screening and grading: The useful minerals are selected in the crushing process or graded by size. Ore Dressing

However, some Swedish fully autogenous mills are so equipped and recently Afton Mines in British Columbia commissioned an autogenous mill with variable drive. Most SAG operations use volumetric ball charges, i.e., % of mill volume occupied by the balls including interstitial volume, of 6-10% depending on the work index of the ore to be milled

Autogenous and Semi

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
