The SAG mills have been mostly used for milling hard gold and copper ores with quartz, ultramafic or green stone as host rocks. The Bond work index of these ores ranges between 12 and 14 kWh/t. Subsequently, SAG mill application has been extended to softer ores, such as bauxite and clayey hard-capped gold ores.

Aperiodic variability is widely observed in nearly all types of accreting compact objects (Fig. 6).Ensemble-averaged Fourier power-density spectra (PDS; Fig. 7) provide a standard tool to analyze such variability.Although theory of the shape of the PDS continua is still quite primitive, we have in hand a useful concept called "self-similar variability" 13.
