Learn more about mon isamill fine grinding technology gold equipment. Mineral Processing Kcgm. KCGM was one of the earliest commercial users in Australia of the IsaMill ultrafine grinding technology The first IsaMill was commissioned at the Gidji Plant in 2001 and a second IsaMill was installed at the Fimiston Plant in 2002 UFG Mills use very small ceramic balls .
He found that fine grinding was well established for such highvalue manufactured products as printer inks, pharmaceuticals, paint pigments and chocolate. Early IsaMill development work. MIM decided to work with Netzsch, which was a pioneer in the fine grinding field, and still a leader.
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.

Ultrafine grinding within an IsaMill. The IsaMill grinds the gold concentrate down to a size (approximately 10 microns) to maximise the rate and efficiency of subsequent oxidation and gold extraction chemistry.
Reducing the specific energy requirements from fine grinding by even a small amount is critical to cost savings and boosting the returns from mineral processing. Glencore Technology has developed, tested and now commercialised conical spacers for their IsaMill™ fine grinding technology that it says have achieved extremely significant reductions in energy draw.
Since then, the 3MW M10,000 has become the most commonly installed IsaMill™. The power installed in regrind and coarse grinding applications has quickly outstripped that used in ultra fine grinding. This remarkably rapid adoption in coarse grinding reflects the robustness and simplicity of IsaMill™ technology.
The IsaMill™ addressed the two major issues of energy efficiency and the resultant downstream metallurgy, primarily through the use of stirred, small, inert grinding media. The first MW IsaMill™ using inert media was commissioned at Mt Isa in 1994 and four MW IsaMills™ became the enabling technology for the McArthur River project ...

IsaMill™ Technology Used in Efficient Grinding Circuits Burford1 and Clark2 High intensity stirred milling is now an industry accepted method to efficiently grind fine and coarse particles. In particular, the IsaMill™, which was invented for, and transformed the fine grinding
In short, IsaMill™ reduces the energy cost, media cost and capital cost of finegrinding. 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
The patented IsaMill is a transformation in grinding technology based on high intensity stirred milling. The IsaMill was developed for fine grained orebodies that needed a step change in processing efficiency to be economic. The IsaMill significantly reduces the energy requirement, and media and capital costs of fine grinding.
