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
