ABSTRACT
Northern Star Resources Limited Jundee Gold Mine in Western Australia operates a comminution circuit that
consists of a primary crusher, 3.85 MW semi-autogenous grinding (SAG) mill, 1.8 MW ball mill and pebble
recycle crusher. In 2017, a secondary crushing circuit was installed to remove the SAG mill throughput
bottleneck and increase production of highly competent underground ore from 1.35 to a minimum of 1.7
Mt/a.
This paper discusses the findings from the trial phase, the circuit design, project delivery, site optimisation,
and the plant performance.
