pH7 Technologies operates a commercial PGM extraction facility in Vancouver and is scaling its mining-sector applications beginning with copper. Its proprietary closed-loop organo-electrochemical process is designed to recover metals from low-grade sulfide ore, tailings, and complex feedstocks that have been historically uneconomic or challenging to process. The company’s proposed copper production approach aims to convert low-grade sulfide ore directly into 99.9% pure copper cathodes on-site while generating green hydrogen as a by-product. pH7 says the process could increase recovery from low-grade resources, extend the value of existing mining assets, and strengthen domestic critical mineral supply chains. Current plans include engineering and technology development phases to produce technical and economic data to support future demonstration and commercial deployment across the Canadian mining sector.
