Description
This article describes an implementation of the Autogenous (AG) and Semi-Autogenous (SAG) mill model originated by Leung (1987) and extended with variable breakage rates by Morrell and Morrison (1996).[1][2][3]
The formulation is referred to in the associated literature as the "Variable Rates" model (Morrell et al., 2001).[4]

The Variable Rates AG/SAG mill model may be invoked from the Excel formula bar with the following function call:
=mdUnit_AGSAG_VariableRates(Parameters as Range, Size as Range, MillNewFeed as Range, MillRecycleFeed as Range, OreSG as Range, BallSizing as Range, RSize as Range, RConst as Range, OreBreakageParams as Range)
Invoking the function with no arguments will print Help text associated with the model, including a link to this page.
