Autogenous Grinding Mining Fundamentals

Autogenous grinding is a process of grinding ore in a rotating cylinder, using large pieces of the same ore Autogenous mills operate mechanically like ball mills; however, the media used for grinding differs Simply put, in autogenous grinding, the media is also the material that is being ground, whereas in other milling methods steel or porcelain balls are used as media Related Stories

The two main objectives for a grinding process are: To liberate individual minerals trapped in rock crystals (ores) and thereby open up for a subsequent enrichment in the form of separation To produce fines (or filler) from mineral fractions by increasing the specific surface Grinding takes place in more “open” space which makes the retention time longer and adjustable compared to
