Le IsaMill est une industrie minérale économe en énergie broyeur qui a été développé conjointement dans les années 1990 par Mines du mont Isa Limited («MIM», une filiale de MIM Holdings Limited et qui fait désormais partie du Glencore Xstrata groupe de sociétés) et Netzsch Feinmahltechnik ("Netzsch"), un fabricant allemand de moulins à billes.
The Evolution of the IsaMill into Magnetite Processing The evolution of IsaMill™ technology from an ultrafine grinding technology to a mainstream and regrind technology has resulted in wide acceptance in many metalliferous applications where utilizing the IsaMill™'s key advantages of energy efficiency, high intensity and circuit efficiency.

An overview of the beneficiation of iron ores via reverse . Iron is one of the most common elements in Earth s crust The primary industrial types of iron bearing minerals include oxides and hydroxides and to a lesser extent carbonates magnetite Fe 3 O 4 hematite Fe 2 O 3 goethite FeO OH limonite FeO OH × nH 2 O and siderite FeCO 3 The genesis of iron ore deposits is variable similar to ...
The former mainly selects magnetite ore, and the latter is mainly used for sorting hematite, mixed iron ore and weak magnetic ore. 6.2 Magnetic separation – cation reverse flotation process The grade of iron concentrate increased from 65.55% to 38.89%, the silica content decreased from 8.31% to 3.90%, and the iron recovery rate was over 98.5%.
Optimising Western Australia Magnetite Circuit Design2.12 Мб. 10: Ernest Henry Magnetite IsaMill/Tower Mill comparison It is clear from Figs.The intermediate magnetic separation step after the ball mill removes about 80% of the silica present in that stream. This results in less silica that has to be ground to 34 Ám.
The magnetite concentrate is pumped via pipeline to the coast and serves as pellet plant feed, eventually being turned into steel in the Whyalla blast furnace. With the addition of a new 3MW IsaMill at the concentrator, the plant has seen increased production from a reduced feed grade, enabling Arrium to treat ores previously stockpiled as waste.
The IsaMill™ is used extensively in base metals, PGM, gold processing and magnetite grinding applications. And the power capacity of an IsaMill ranges from 75kW to 3.8mW. While it's best known for achieving unequalled results in 'ultrafines', IsaMill™ is in fact an all-rounder, and roughly half our mills are processing feeds greater than ...
A magnetite middling was used to compare the liberation effect of the magnetite fine ground by a vertical stirred mill and a ball mill. The magnetite middling contained a high content of magnetite intergrowth with the particle size mainly distributed in the range of 40–150 μm.The new generated −38 μm products were concentrated by magnetic separation.
The testwork at AMMTEC for this Western Australian magnetite deposit consisted of: Pilot autogenous primary milling, laboratory work (Levin test) and pilot secondary ball milling, laboratory and limited continuous secondary IsaMill testing, laboratory tertiary, limited continuous and pilot IsaMill testwork,
The newest application for the IsaMill is in magnetite grinding. An M10000 is being installed at Xstrata Copper's Ernest Henry mine in Queensland, Australia, where a new circuit at the plant will use magnetite-rich tailings from the copper concentrator to produce a high-grade iron concentrate for export.

The pilot plant achieved 34.2% mass yield, at 69.0% Fe, 2.2% SiO2, from an IsaMill grind of 80% -45 μm. This product quality will compare favourably to other leading direct reduction (DR ...
Among these has been IsaMill technology which has allowed the Australian Magnetite industry to take advantage of improved energy efficiency coupled with tight product size distributions that originally made the IsaMill so attractive to the base metals processing industry.
This has necessitated some creative changes to the flow sheet that previously had a 937kW Vertimill regrinding a rougher concentrate to 40 microns. EHM is able to utilise an existing M10 000 3 MW IsaMill previously used for magnetite processing, to provide a quick convenient solution without large scale capital expenditures.
The magnetite circuit at EHM is designed to treat 6 Mtpa and produce 1.2 Mtpa of magnetite concentrate. A 3 MW, M10,000 IsaMill™ operates in the circuit, treating magnetic rougher concentrate sizing between 150 and 200 μm and reducing it down to 40–45 μm, before it is further cleaned to produce the final grade concentrate ( Larson et al ...

In 2014, SIMEC Mining commissioned a 3 MW M10000 IsaMill at their magnetite concentrator in the South Middleback Ranges of South Australia. The IsaMill is designed to grind feed with a particle size of 60 µm to generate a product with a particle size of P 80 of 32 µm at a throughput of 300 t/h [ 7 ].
Whyalla Magnetite Expansion Project Scope of Work GR Engineering was contracted by Leighton Contractors to undertake the engineering, design, procurement, construction and commissioning of an upgrade to the existing Magnetite Concentrator Plant at the Iron Duke Mine Site.
With the expansion of magnetite projects in Australia has come the opportunity to take advantage of newer technologies that were not necessarily available when the magnetite industries of North America and Europe were maturing. One of these technologies is the IsaMill, originally developed for the economic treatment of ultra-fine grind (UFG) duties of Mount Isa Mines.
