Also, fundamental studies around this area have been neglected over the years. The basic concept of the mill acoustic emission could support and improve the understanding and optimisation of AG/SAG mill. It further enables recent mining industry drive for reduced on-site footprint, owing to health and safety concerns.

Commissioning of the Cadia Hill SAG mill Circuit followed a project Research and Development exercise in July 1998. The SAG mill quickly reached 90% of the design rate but it became evident that the mill would not meet design throughput at the design operating conditions of ball and rock charge, mill speed and power draw. Cadia Hill staff …
