At full scale, by varying the IsaMill™ throughput (at standard operating mill speed) it was demonstrated that a reduction in specific energy was observed of approximately 13% at a P 80 target grind of 22 µm increasing to 17% at a P 80 target of 18 µm. There was an accompanying decrease of about 22% in drawn mill power.
This laboratory work presents a study of the effect of ultrafine grinding on the gold recovery of a highly refractory gold concentrate. The particle size of the concentrate was P80 = 46 µm and the main species present were quartz (%), dolomite (%), pyrite (%), arsenopyrite (%) and 112 g/t gold. After optimizing hydrated lime and lead nitrate additions, standard cyanidation ...
The IsaMill tests were performed at another copper mine, which has the flowsheet depicted in Figure 3. As indicated on t he illustration, the mill aimed to process the cyclone underflow stream to replace the ball milling application. Figure 3. Flowsheet of milling and beneficiation circuit of the copper mine with IsaMill.

A modified mill used by AMMTEC/ALS is a 203 (ID) × 300 mm variable speed mill using kg of steel charge. IsaMill Signature Plot. For scaleup of an IsaMill, a 4 litre IsaMill is operated in a recirculating mode with a batch of slurry passed through the mill and then fed back through the mill in a number of recycle steps.
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.

The IsaMill is a stirredmedium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older highthroughput mills (such as ball mills and rod mills ). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill. [7]
Currently, Washington has several permitted metal mines, but only one of them is operational—the Buckhorn Mountain gold mine in Okanogan County, managed by Kinross Gold Corporation. The mines shown are by no means all of the metallic mines in Washington. The remainder of the mines existed prior to the Metals Mining and Milling Act was signed.
