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 energy use and media ...

How HPGR improves gold recovery. There are two main ways mines recover gold ore from the gangue, and HPGRs can assist with each process. One of them is heap leaching and for mines using this process, we've found that the most efficient setup is to have a HPGR perform tertiary grinding immediately prior to recovery, completely avoiding the use of a ball mill with the help of a partial product ...
