The IsaMill also incorporates a proprietary particle separator, minimizing overgrinding of the particles as the ground particles pass through the separator, while reticulating the oversize material back into the mill. An IsaMill can be provided as part of a complete grinding plant for projects, which reduces the installation time for the project.
Nov 08, 2018 Hailes IsaMill will process up to 55 th of Pyritic feed. Its a hard ore so the mill is going to get some good use, he said. Although Haile Golds recoveries have consistently averaged in the low 80 range, the grind size achieved by other equipment has only been 19 microns.

The new, reimagined Golden Mill will continue the community gathering place tradition with new life as a spot for locals and visitors alike to enjoy live music, events and pop-up markets, while enjoying food from five local food concepts and beverages from a self-pour wall that boasts over 50-taps of home-grown brews, wines, and housemade cocktails.
In the year 2000, Kalgoorlie Consolidated Gold Mines KCGM became the first external user of the technology with a 1.1 MW M3000 IsaMill installed to supplement the roaster capacity at its Gidji Processing Plant. The IsaMill was used to ultra-fine grind about 10 th of pyrite flotation concentrate to 10-12 m prior to gold cyanide leaching.
Jul 06, 2017 This project will be the 14th mill we have in a gold pre-leaching grinding duty, and highlights the need for delivering high levels of liberation for good gold recovery, such as what we see in operations at Las Lagunas and Ararat gold operation, that use the IsaMill in their Albion Process circuits.
Aug 01, 2015 The Isamill is a horizontal stirred media mill used for fine and ultrafine grinding of slurry transported rock particles. The charge motion is analysed using two different approaches, 1 a fluid only model, and 2 a 1-way coupled DEM SPH model.The flow pattern when the classifier is closed is regular with a pair of oppositely oriented vortices between each pair of grinding discs.

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.
Traditional fine-grinding mills in mineral processing rely on the use of steel medium for particle size reduction. The IsaMill a horizontal stirred mill with a 3,000-L net chamber volume and a ...
The IsaMill can be operated in open circuit at high slurry density, which is a key advantage for the leaching circuit, as the entry of water to the leach is limited, simplifying the water balance. The IsaMill uses inert ceramic grinding media ranging from 1.5 mm to 6.0 mm, that produces clean, polished mineral surfaces resulting in ...
Jul 31, 2013 Here is an energy plot AKA an IsaMill Signature Plot AKA a Ultrafine Grinding Test Report. This test is performed using a Netzsch Grinding lab mill. I also include links to great articles about this powerful ultra-fine grinding technology. 1 IsaMill- 11 Direct Scaleup from Ultrafine to Coarse Grinding. 2 The Benefits of IsaMill Testing.
The mill, the M3000 IsaMill, was quickly installed in other circuits at this concentrator, and was installed in the McArthur River Concentrator in 1995 Johnson et al, 1998. Later, in 1999, it was commercialised and sold outside of the Xstrata group. Since commercialisation of the IsaMill, there are now over 50MW of installed IsaMills

Apr 23, 2016 Run the IsaMill empty no water or media for 5-10 minutes to warm up the bearings and seal. Then proceed to run the mill empty at 1500rpm for an additional 10 minutes and measure the cumulative power draw using the watt-hour meter Wh and stop watch. From the time and total energy values, the no load power draw can be calculated.
