In this work, the purpose was to study the impact of variations in feed ore properties on the performance of a primary autogenous grinding circuit by ore characterisation and simulation.
The Cretaceous plant at the Hill Annex mine of the Jones Laughlin Steel Corp. was designed with a wet autogenous mill for grinding low grade iron ore so that it could be concentrated by spirals and flotation cells. The plant, on the west end of the Minnesota''s Mesabi Range, went into operation in June 1961, and preliminary operating and metallurgical information describing the performance ...
Historically, the lowest operating cost was achieved by multistage fully autogenous grinding with integrated magnetic separation steps between the stages. The major benefit of fully autogenous grinding is the elimination of steel grinding media costs and the need to discriminate between steel and magnetite in coarse magnetic separation.
Reducing Grinding Energy and Cost Magnetite Iron Ore Design Case Study A. Jankovic and W. Valery Process Technology Innovation, PO Box 1028, Eagle Farm Qld, 4009, Australia ABSTRACT:Efficiency of the comminution operations is traditionally assessed based on operating cost and energy consumption.
semiautogenous grinding (SAG) and metallurgical pilot plants on iron ores, including extremely large plants treating up to 1,000 tonnes of ore and lasting for 6 months. Many complex circuits using autogenous grinding, desliming, magnetic separation, gravity separation, selective flocculation, and flotation have been run in our laboratories.
autogenous grinding mill crushing process iron ore grinder Autogenous Semi Autogenous Grinding Circuits 911 Metallurgist. Autogenous grinding is favored when the ore is quite competent and a An autogenous or semiautogenous circuit, as the name implies, uses the ore itself to assist in the grinding process.
The Effect of Microwave Treatment on Dry Grinding Kinetics ... The effect of microwave treatment on the grinding kinetics of an iron ore was assessed using monosized materials of þ mm, þ mm, þ mm, and þ mm as feed.

chamber for iron ore grinding. The singlecompartment mill is ideal for the grinding of finegrained feed material. One typical application is the combined grinding and drying of iron ore concentrate with a high feed moisture content (up to approx. 8 %). Highefficiency separators minimise the power consumption of dry grinding systems.
Autogenous (AG) Grinding Mill, SemiAutogenous ... Reducing Grinding Energy and Cost Magnetite Iron Ore... •Conventional three (and four) stage crushing followed by primary and secondary milling, • Primary crushing followed by wet SAG or AG milling and ball or pebble ...
Iron ore grinding and classification. ... Historically, the lowest operating cost for grinding finegrained ores was achieved by multistage fully autogenous (AG) grinding (Koivistoinen et al., 1989) with integrated magnetic separation steps between the stages. The major benefit of fully AG grinding is the elimination of steel grinding media.
1. Introduction. In comparison to conventional tumbling mills,, rod and ball mills, the grinding media in an autogenous mill derive from the feed ore itself (Rowland and Kjos, 1978).Any change in feed ore properties will therefore affect the grinding charge and thus, the breakage mechanisms within the mill.
Autogenous or autogenic mills are socalled due to the selfgrinding of the ore: a rotating drum throws larger rocks of ore in a cascading motion which causes impact breakage of larger rocks and compressive grinding of finer particles. It is similar in operation to a SAG mill as described below but does not use steel balls in the mill.
