BHP Group LimitedBHP pilots innovative copper recovery tech at Arizona site, potentially improving extraction efficiency and sustainability.

BHP and SiTration, a Massachusetts Institute of Technology spin-out, are planning two pilot programmes of copper recovery technology at BHP's site in the Globe-Miami district of Arizona. The initial phase will be a small-scale trial running over one month, followed later this year by a larger deployment expected to produce up to two tonnes of commercial-scale copper cathodes over two months. The companies aim to extract copper from legacy mining water at the historic Copper Cities site, which produced nearly 400,000 tonnes of copper between the 1950s and early 1980s. SiTration has already conducted bench-scale tests on feedstock from Copper Cities that reportedly produced LME Grade A copper without chemicals, without new waste products, and with energy consumption below 3–4 kilowatt-hours per kilogram. Both companies have signed an agreement to collaborate on the pilot programme and evaluate future opportunities if results are positive.
