Applying CiDRA’s technology as a grind circuit rougher will help remove coarse material from the grind circuit circulating loads, enabling an increase in plant throughput without increasing total power consumption. This translates to a 20% reduction in energy per unit ton.

Worley will provide FEED services for the project.

“OZ Minerals is excited to be working with the CiDRA and Worley teams on this world-class project. We view the FEED study as a crucial first step for the implementation of CiDRA’s grind circuit rougher technology to enable us to increase our plant throughput while maintaining industry leading recoveries at Carrapateena,” said Joe Seppelt, manager – Processing at Carrapateena.

Upon final investment decision and selection by OZ Minerals for the project to progress, CiDRA and Worley expect to negotiate the subsequent detailed engineering and execution phases of the project.

“Since early 2022, we have worked closely with OZ Minerals to evaluate and innovate our P29 technology to help meet their long-term expansion goals. We are pleased with our partnership with Worley to deliver our first-of-a-kind technology in a collaborative and efficient way,” said Paul Rothman, president of CiDRA.
