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 ...

An ultrafine grinding (UFG) circuit of eight FL VXP mills has been successfully optimised at the Barrickoperated Kibali gold mine in the Democratic Republic of Congo. The first four VXP mills were installed in the Kibali gold recovery plant in 2014.
The grinding operation of rock gold mine usually adopts onestage or grid ball mill + overflow ball mill for twostage grinding. The second stage grinding operation forms a closed loop with a spiral classifier or a hydrocyclone to ensure the grinding fineness. In general, only the dissociation of the sulfide ore monomer is required for gold ...
