MINERALS & METALLURGICAL PROCESSING 95 Vol. 28 No. 2 • May 2011 Ultrafine grinding mills have been in use for many years in a large number of …...Use of ultrafine grinding in hydrometallurgical processes. In metallurgical processes, ultrafine grinding can be used immediately prior to the agitation-leaching stage. Extensive mechanical activation of the material (changes in its chemical and physical properties) can occur in some cases when the minerals' structure is mechanically disturbed.

Presented at the …...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. Overall …
