BHP Commissions Eriez® for HydroFloat® coarse particle flotation plant at Carrapateena mine
27.08.2025BHP and Eriez announced the successful commissioning of a HydroFloat coarse particle flotation (CPF) plant at Carrapateena mine in Australia. BHP, a global resources company focused on sustainable mining and innovation, and Eriez, a leader in advanced mineral processing solutions, see this milestone as representing a significant advance in sustainable, high-efficiency mineral recovery for the worldwide mining industry.

Completed through a close collaboration among BHP, Eriez, VOLPRO, and Paradocs Metallurgy, the CPF project integrated HydroFloat technology into the existing processing circuit. From installation through commissioning and optimization, the teams worked together, meeting performance targets on an accelerated schedule and within budget.
HydroFloat CPF recovers coarse, high-value particles that conventional flotation often loses to tailings, increasing metal recovery and plant throughput while supporting more sustainable operations and better tailings management. “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. “The trust, transparency, and teamwork with the Carrapateena operations team, VOLPRO, and Paradocs have raised the bar for future HydroFloat deployments.”
The plant is fully operational, both producing results in line with expectations and paving the way for broader adoption of HydroFloat CPF in base and precious metals processing. BHP and its partners will continue to refine the technology and CPF flowsheets, share insights, and evaluate opportunities to expand HydroFloat applications across other operations.
