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 ...

The Mill recovered metals from the ore by gravity separation and by selective flotation. Sulfide ore minerals were concentrated by froth flotation, a method used in the early twentieth century that allowed processing of ores. The original mill equipment is still in working order. It is the only intact and functional mill of its kind in Colorado.

Grinding is the second step of mineral processing and the last stage of the comminution process. The product from a crushing unit is fed to a mill in order to decrease the particle size (sometimes even to 10 microns) for subsequent processing. The reduction ratio is usually large (8 to 25:1 sometimes 500:1). The purpose of grinding differs with ...
