BHP and Eriez Launch Innovative HydroFloat Technology at Carrapateena

BHP, a leader in sustainable mining, and Eriez, an expert in advanced mineral processing, have successfully launched a HydroFloat coarse particle flotation (CPF) plant at the Carrapateena mine in Australia. This development marks a significant achievement in the global mining sector, enhancing mineral recovery efficiency while promoting sustainable practices.

The project was completed through a collaborative effort involving BHP, Eriez, VOLPRO Pty Ltd, and Paradocs Metallurgy. Together, these teams integrated the HydroFloat technology into the existing processing circuit. The initiative was notable not only for its accelerated timeline but also for staying within budget, meeting all performance targets during installation and commissioning.

The HydroFloat CPF technology is designed to recover coarse, high-value particles typically lost in conventional flotation processes. This advancement increases metal recovery rates and plant throughput, supporting a more sustainable operational framework and improved tailings management.

Significant Milestone for BHP’s Copper Operations

Anna Wiley, asset president for BHP Copper South Australia, highlighted the importance of this milestone. “We are making great progress in building our South Australian copper province. This is a massive achievement for our team and a significant step forward for our Copper SA operations,” she stated. Wiley emphasized that the HydroFloat technology exemplifies innovative thinking and investment in productivity, which are essential for the company’s future success in South Australia.

The successful implementation of the HydroFloat CPF is a first for BHP, with substantial implications for processing capacity at the Carrapateena site while maintaining recovery rates. “BHP’s focus on innovation and operational excellence was critical to the success of this project,” said Jose Concha, global director of mining products at Eriez. He praised the collaborative spirit among the Carrapateena operations team, VOLPRO Pty Ltd, and Paradocs Metallurgy, noting that their teamwork has set a benchmark for future HydroFloat deployments.

Future Prospects for HydroFloat Technology

The HydroFloat plant is now fully operational, producing results that align with expectations. This success paves the way for broader adoption of HydroFloat CPF in both base and precious metals processing sectors. As this technology continues to evolve, BHP, Eriez, and their partners are committed to refining the CPF flowsheets, sharing insights, and exploring opportunities to expand the application of HydroFloat across other mining operations.

This collaborative project not only exemplifies innovation within the mining industry but also reflects a commitment to sustainable practices that could redefine mineral processing in the years to come. For further information, visit www.Bhp.com and www.Eriez.com.
