Autogenous Grinding - Mining Fundamentals

The term autogenous grinding came about due to the concept of self-grinding of the ore. It is also referred to as "Run of Mine" or ROM grinding. A sturdy, rotating drum throws larger rocks of ore in a cascading motion, causing impact breakage of similar smaller

Small-Scale Continuous SAG Testing Using the Macpherson ...

autogenous (SAG) mills were first used on ores in the 1950s, but they were not seriously considered by the mining industry until the 1960s. By the 1970s, most designers of new plants considered AG/SAG grinding, even if it was not used in the final grinding circuit design. In the 1980s, many of the grinding plants that were built used FAG

Autogenous Grinding Article about Autogenous

In comparison to grinding with steel rods or balls, autogenous grinding has the following advantages: (1) the crushing of the ore before milling is simplified and made less expensive, (2) the expenditure of steel rods or balls is eliminated or reduced, and (3) the technological efficiency for the concentration of some ores is improved as a result of less overgrinding of a valuable mineral.
