Arizona Revives Copper Mining with Biocatalysis at Gunnison Copper's Johnson Camp
In the desert east of Tucson, Arizona, Gunnison Copper, in partnership with Rio Tinto's Nuton, is restarting copper production at the previously halted Johnson Camp mine. Utilizing microorganisms and sulfuric acid, the project aims to extract copper from low-grade ores. The revival is driven by technological advancements and rising demand for copper, essential for electrical devices, amidst efforts to boost U.S. raw material production.
