Ten Sixty Four Limited (TSFL) is a publicly listed Australian-based gold producer operating in the Asia Pacific region. Since their acquisition with Philsaga Mining Corporation in 2021, the company embarked on an aggressive growth mission, with the Philsaga Co-O mine as their flagship site.

TSFL, a long-term Weir Minerals customer, was experiencing high circulating load in the mill circuit and requested that Weir Minerals review the performance of the Cavex® 250CVX10 hydrocyclone cluster installed in the gold processing plant. Through their investigations our team found the main issue was the SAG mill grinding performance.

We conducted a thorough study of the mill operating conditions, aided by simulation software such as MillTraj and DEM (Discrete Element Method) modelling. Through this investigation, our team was able to fully understand the grinding environment inside the mill and engineer a mill lining system that generated the optimal grinding trajectory.

A Vulco® R63 composite mill lining system was chosen to replace the incumbent steel liners, and a Warman® MCU® 200 pump fed through Linatex® premium rubber lined spools to replace the underperforming competitor pump. Our team also upgraded the 10 pack Cavex® 250CVX10 hydrocyclone cluster to a 12 pack Cavex® 250CVX10 hydrocyclone cluster to improve classification efficiency and spares availability.

The result was an increase in throughput by 20% with no surprise downtime.
