Copper mining firm Rio Tinto is partnering with Amazon to provide copper from a southern Arizona mine for the tech giant’s next wave of U.S. data centers.
Rio Tinto explained Thursday that under a two-year agreement, Amazon Web Services will use the copper from the Johnson Camp Mine in Cochise County, which is owned by Gunnison Copper.
“Data centres use copper in a wide variety of applications, including electrical cables and busbars, windings in transformers and motors, printed circuit boards, and heat sinks on processors,” Rio Tinto explained in a news release.
The mine will use Nuton’s proprietary “bioleaching” method to use less water and have lower carbon emissions. According to the WSJ report, the tech uses bacteria and acid to extract copper from ore that would otherwise be too expensive to process.
