Energy Use of Fine Grinding in Mineral Processing SpringerLink
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
About Glencore Technology
About The first stage of the Albion Process™ is fine grinding of the concentrate, which introduces a high degree of strain into the sulphide mineral lattice The number of grain boundary fractures in the mineral increases, enabling leaching under atmospheric conditions Fine grinding is carried out in energy efficient IsaMills™
