    9.1. Introduction. Disintegration and size reduction of some ores is possible in tumbling mills without the aid of grinding media. Grinding mills in which comminution takes place without grinding aids are known as autogenous grinding (AG) mills or fully autogenous grinding (FAG) mills. These mills use large lumps of rock as the grinding media.

    Free-milling gold ores are defined as an ore from which standard cyanidation (which takes about 20-30 hours) can extract more than 90 of the gold under the condition that the ore size is 80 < 75 µm (Joe Zhou 2004). Complex ores meanwhile require significantly higher cyanide or oxygen levels to attain an economic recovery (Brooy 1994).
