### Energy Use of Fine Grinding in Mineral Processing

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 a mill’s energy budget.

### Energy Use of Fine Grinding in Mineral Processing

AG or SAG mill, intermediate grinding to a ball mill or tower mill, and ﬁne grinding to a stirred mill such as an Isamill or Stirred Media Detritor (SMD). Of course, various exceptions to these typical values can be found. In ﬁne grinding, a material with an F80 of less than 00 lm is comminuted to a P80 of 7 to 30 lm. (P80s of 2 lm are at least claimed by equipment manufacturers.) The
