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.
Since early 2001, Kalgoorlie Consolidated Gold Mines (KCGM) has successfully operated an ultra fine grinding (UFG) circuit to supplement its roaster capacity for the treatment of the refractory gold flotation concentrate. A second UFG mill was installed in 2002 taking the total UFG capacity to over 20tph while grinding to 11-12 microns and achieving over 90% gold recovery.
The Anglo Gold Ashanti (AGA) Sunrise Dam Gold Recovery Enhancement Project (REP) was an upgrade project to the existing process plant to increase gold recovery. The project required the existing screened cyclone overflow to be redirected into a new flotation and ultra-fine grinding circuit, producing concentrate up to a rate of 400000t/a.
From these sets of data, it can be seen that the grinding fineness has a greater impact on the gold leaching rate. With the increase of the grinding fineness, the gold leaching rate increases first and then slowly. It can indicate that increasing the grinding fineness is beneficial to release of gold minerals from the inclusions.

Fine Grinding Implementation at the Cracow Gold Processing Plant Fine Grinding Implementation at the Cracow Gold Processing Plant The Cracow Gold project is located 500kms north west of Brisbane, in the Banana Shire of Queensland. In 2016 Evolution Mining (Evolution) undertook an investigation into maximising the gold recovery from the CIP Plant.
The gold in refractory gold ores is usually wrapped in sulfide minerals in the form of fine particles. It is difficult to dissociate the gold monomer by the usual fine grinding (p80 = 53-75um). In the process of gold leaching, the leaching agent can not contact with gold, resulting in low recovery rate of gold and no economic value.
