Vale Base Metals accelerates Salobo copper expansion via coarse particle flotation, targeting +30kt/year output and earlier 2028 start
Executive summary: Vale Base Metals confirmed the advancement of the coarse particle flotation (CPF) project at the Salobo mine to boost copper production capacity, with regulatory approval granted and the start date moved to H1 2028. The upgrade could add nearly 30,000 tonnes of annual copper output—equivalent to ~10% of Salobo’s current capacity—enhancing Vale’s competitiveness in the global copper supply chain amid rising demand from electrification.
Who is involved: Vale Base Metals (operating unit of Vale S.A.), Salobo mine operations, Brazilian regulatory authorities.
Likely next: Engineering and procurement phase to begin shortly, with construction expected to precede the H1 2028 start date; no further delays indicated.
Vale Base Metals’ decision to fast‑track the coarse particle flotation (CPF) upgrade at the Salobo copper mine reflects a push to lift output without expanding the pit’s physical boundary. By targeting an additional ~30 kt of copper per year and raising ore‑processing capacity by about six million tonnes, the project hinges on a technology that treats larger particles directly, cutting the energy‑intensive grinding stage and potentially improving recovery rates. The start date has been moved to the first half of 2028, pending the usual regulatory clearances, which brings forward the expected cash‑flow contribution by roughly a year compared with the prior schedule. From a market standpoint, the incremental volume represents a modest but tangible addition to Vale’s copper portfolio, helping the company meet steady global demand while potentially lowering unit production costs. The earlier commissioning also reduces execution risk exposure to commodity price swings and may free capital for other initiatives. Near‑term, investors will watch for permitting milestones, any updates on capital expenditure, and how the CPF performance translates into actual mill throughput once the plant is operational.
