A steep particle size distribution is produced in the mill. The 98% passing size in the mill is typically less than 2.5 times the 80% passing size, and very little coarse material enters the leaching circuit, resulting in very high leach recoveries.

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 rated motor power of 1,120 kW) has successfully adopted a novel product-separator design, which has led to a major revision of medium use in fine …
In short, IsaMill™ reduces the energy cost, media cost and capital cost of fine-grinding. 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.
Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of …

The M15000 IsaMill™ will be operating in a quaternary milling duty treating lead pre float tail prior to lead flotation and will reduce particles from 150 to 60 microns.
Immediately start the mill at 1500 rpm (nominal) and start the timer. Once slurry has been exiting the mill for 15 seconds direct the mill product hose into the second (empty) tank. Turn on second tank …
Ball milling simply cannot produce a 10 micron product at any practical power consumption. In this case the IsaMill has extended the economic range of grinding from about 20-30 microns to 10 microns – enabling technology if a 10 micron grind is needed, as it was for the KCGM cyanide leach.

IsaMill™ operations can take advantage of this feature, which translates to an ability to use a low cost, but relatively low quality grinding media such as silica sand, river pebble, smelter slag or fine primary mill scats (autogenous milling). This means low media cost, with power efficiency still better than conventional grinding.
The total productivity of ultrafine grinding exceeded 9-12 t/h when the concentrate was ground to a P80 of 10-12 µm, and a gold recovery rate of more than 90-92% could be achieved through ...

of the IsaMill™ is one tenth of the equivalent ball or tower mill. The high intensity means short residence times, preventing overgrinding and giving a sharp product size distribution. » IsaMill™ advantages 7 Horizontal Design plug-˚ow design. This avoids short circuiting and makes the mill far less sensitive to process disturbances.
Immediately start the mill at 1500 rpm (nominal) and start the timer. Once slurry has been exiting the mill for 15 seconds direct the mill product hose into the second (empty) tank. Turn on second tank agitator as soon as level builds up in tank. At about the midway point of the pass (i.e. when the two tanks have about equal level): a.
The significance of the PPL-C installation is that it is the first IsaMill to be installed in a coarse, mainstream grinding application as a ball mill alternative, the company said.

The IsaMill™ is a horizontal, high speed stirred mill that operates with very high power intensities (up to 300kW/m3) compared to ball or tower mills (with less than 40kW/m3). …
The large scale of the IsaMill™ makes that efficiency available to mainstream grinding. The high energy efficiency of stirred mills compared to ball mills is well understood. The use of tower mills as an energy efficient alternative to secondary and regrind ball milling became a common inclusion in the latter part of the previous century.
