Gold Ore Mining. Placer gold mining mainly refers to mining from the land surface or river or underground. It mainly uses gravity separation because its density is much bigger than other minerals. Compared with placer gold, rock gold ore has higher gold content and mining value, but the beneficiation process of rock gold ore is much more complicated …

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 …
