IsaMill Ultrafine Grinding for a Sulphide Leach Process of refractory pyrite in Mt Isa's lead/zinc ore resulted in a gradual decrease in concentrator metallurgical performance over time. Work had been conducted at Mt Isa between 1975 and 1985, involving regrinding to ultra fine sizes to increase liberation, using conventional grinding technologies.
Ultrafine grinding is used to liberate gold finely disseminated in metallic sulfides. KCGM is the first gold mine using ultrafine grinding followed by cyanidation (Ellis and Gao, 2002 ). The gold sulfide concentrate is grind with an IsaMill to a P 80 of 10–12 μm.
An IsaMill operated in continues mode was chosen for the purpose of mechanical activation because this type of stirred-ball mill has been successfully used for ultrafine grinding. Because of its quick response to CO2 sequestration, a direct aqueous mineral carbonation process was used to test the extent of
Ultrafine Grinding and the IsaMill™ Technology - Glencore Technology supplies the IsaMill™ technology to mining operations around the world, with over 110 mills installed worldwide. The IsaMill™ uses a very high energy intensity of 300kW/m3 in the grinding chamber, resulting in a small footprint and simple installation.
Another report from Quebec Mines conference, this time by GREG RASMUSSEN (XT) IsaMill technology was developed from the stirred milling technology of Netzsch Feinmahltechnik in the 1990's for use in the fine grained lead zinc ore bodies of Northern Australia in a drive to bring about a step change in grinding efficiency required to make these ore bodies economic …
The definition of ultrafine grinding is broad and vague, referring to nano-sized grinding in some specialised industries but in this book, ultrafine grinding for the mineral industry will refer to sizes less than 20 μm.
Compared to conventional grinding, ultrafine grinding was reported to increase the zinc recovery by 10 %. The IsaMill, which has been developed in partnership with Netzsch Feinmahltechnik, is a high-intensity (up to 300 kW/m3) horizontal disk mill with 8 grinding chambers in series.

IsaMill™ technology was developed from Netzsch Feinmahltechnik stirred milling technology in the early 1990s to bring about a step change in grinding efficiency that was required to make Xstrata's fine-grained lead/zinc orebodies economic to process. From small-scale machines suited to ultrafine grinding, the IsaMill™ has developed into
Development of IsaMill technology at Anglo Platinum concentrators The potential benefit of ultra-fine and fine grinding, (UFG), has been identified for various applications at Anglo Platinum Concentrators over many years. An ongoing programme to investigate the technology has been running intensively for the last seven years.
Glencore's IsaMill™ is an internationally proven Ultrafine Grinding (UFG) Technology in the Mining Industry. The NETZSCH LME-4 laboratory unit has the same internal dimensions and workings as the IsaMill™ M4, and it is designed for laboratory testing purposes for pilot/industrial IsaMill™ applications.

Of specific interest in the Mount Isa operations is the wide choice of grinding media available for use in the IsaMills. Mt Isa has variously used heavy media plant reject and lead or copper smelter slag for grinding media.

"The IsaMill was developed for fine-grained ores that required at least double the grinding efficiency of ball or tower milling to be economic. This was achieved, but in practice, the benefits of using inert media (eg sand, slag, ore, ceramic) have proven to be at least as important as the higher grinding efficiency.
IsaMill development and operation is reviewed. Results from test work to produce a feed stock for both straight cyanidation and sulphide leaching are discussed, with emphasis on energy consumption, product size and leachability. A number of options for ultrafine grinding and leaching are also discussed.
