Comminution Circuits for Gold Ore Processing
Both technical and operational considerations are reviewed; while gold ore comminution is broadly similar to like-sized circuits for other mineral processing applications, specific considerations applicable to gold circuits are highlighted. Although significant production of gold comes from both heap leaching (including run-of-mine and crush ...

Energy Use of Fine Grinding in Mineral Processing
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 …
