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 100 microns.
Grinding. Eight consecutive grinding chambers, patented product separator and short residence times means the mill constantly delivers sharp product size distribution without external classification. The IsaMill™ is a closed mill. Slurry travels through the mill in a 'plug' flow pattern through consecutive grinding
The IsaMill is an energy-efficient mineral industry grinding mill that was jointly developed in the 1990s by Mount Isa Mines Limited and Netzsch Feinmahltechnik, a German manufacturer of bead mills. The IsaMill is primarily known for its ultrafine grinding applications in the mining industry, but is also being used as a more efficient means of coarse grinding. By the end of 2008, over 70% of the IsaMill’s installed capacity was for conventional regrinding or mainstream grinding
Haile Gold IsaMill. Dating back to 1827, the Haile Gold Mine is one of the first operating gold mines in the United States. To improve the leach recovery of the flotation concentration OceanaGold proposed installing a M10,000 IsaMill™ from Glencore Technology for ultrafine grinding duties. The installation of the unit maximises recovery rates,

The large gold mine, owned by AK Altynalmas, treats over 2Mt/y of ore, and has purchased a M5000 IsaMill to be installed in its gold operation. Paul Telford, general manager at Glencore Technology, said: “Our IsaMill is highly energy efficient, and miners all over the world need this type of technology to modernise their operations as
The 3 MW 10,000 IsaMill comes with an IsaCharger™ media delivery system, as well as commissioning services from Glencore Technology. It will be the 50th M10,000 installation. Heron’s Managing Director Wayne Taylor said: “The arrival of the IsaMill marks the step change in technology to be applied to the Woodlawn zinc-copper project.
The plant is designed to recover refractory gold concentrate recovered from the Zod Gold Mine, located on the eastern side of the country. The lump sum design and supply package involves the provision of an M3000 IsaMill™ grinding package, twelve ZipaTanks™ modular leach and slurry storage reactors, a 10 m diameter high rate thickener, 120
Keramax® MT1TM grinding media has been tested and verified using laboratory, pilot and full-scale IsaMills. The first industrial application combining Keramax® MT1TM and IsaMill technology was successfully commissioned at Kumtor’s Gold Mine in Kyrgyzstan in late 2005. Many have followed since then, with Anglo Platinum being the
The latest order on this sector was awarded by Anglogold Ashanti for a machine of size 750/20-1850 for grinding 1775 tonnes of gold ore per hour. 4 IsaMill TM developments. A 2008 market review dealing with the grinding of hard rock  already discussed developments on the field of regrinding and the IsaMills TM employed for this purpose
