The use of a partial secondary crushing circuit provides a flexible way to optimise existing SAG comminution circuits limited by rock competency or enables optimal processing of an ore through second hand equipment not specifically selected for that ore. This paper details the process involved in designing a partial secondary crushing circuit using the recent installation at Mt Rawdon Gold Mine in Queensland as an example._x000D_
