BHP Commissions Eriez for HydroFloat Plant

BHP and Eriez have completed commissioning of a HydroFloat® coarse particle flotation (CPF) plant at the Carrapateena mine in Australia. The project is presented as a step forward in mineral recovery, combining sustainability goals with efficiency improvements. By integrating HydroFloat into the existing processing circuit, BHP and Eriez aim to demonstrate the potential for higher metal recovery rates while reducing losses to tailings.

The initiative was delivered in collaboration with VOLPRO and Paradocs Metallurgy. According to the companies involved, the work was completed on an accelerated schedule and within budget, with the new plant now operating as part of Carrapateena’s broader processing system. HydroFloat CPF is designed to capture larger, high-value particles that conventional flotation methods often miss, a development considered significant for throughput gains and long-term resource use.

“BHP’s focus on innovation and operational excellence was critical to the success of this project. The trust, transparency, and teamwork with the Carrapateena operations team, VOLPRO, and Paradocs have raised the bar for future HydroFloat deployments.” said Jose Concha, Global Director of Mining Products at Eriez.
