The double rotator mills consist of a twin-chamber mill (with sides for coarse and fine-milling), with both sides discharging to a common air-classification system. Operation of Goldstrike's system is well described by Buckingham et al. (2001). Newmont's Minahasa gold operation employed an Aerofall SAG mill followed with dry ball-milling.

Gold usually occurs in these ores as discrete particulates (<0.1 µm in diameter) within sulfide minerals (mainly in pyrite and arsenopyrite) (Hausen, 1981; Radtke, 1985; Hausen et al., 1986; Wang et al., 1992, 1994). In gold ores, pyrite and arsenopyrite often occur in three morphological types: coarse, porous (blastic) and fine-grained.

The mineralogy of gold is summarized in Tables A and B. A distinction is made between gold minerals (Table A), in which gold is a major constituent, and other minerals that contain gold essentially as a trace or minor element (Table B). Both types are important in gold processing. The number of valid gold minerals presently stands at about 30.
