pH7 Technologies Inc., a Canadian company, has raised $25.6 million to scale and commercialize its electrochemical extraction technology for the mining sector, focusing initially on copper. This technology enables the economic recovery of metals from lower-grade ores and complex feedstocks, potentially unlocking new sources of copper, nickel, and platinum group metals.

Funding will support commercial deployments and demonstrations at global mining operations. The proprietary closed-loop organo-electrochemical process allows for the extraction of metals from low-grade ores and tailings without modifying existing leach processes. The electrochemical module generates in-situ oxidizers to enhance metal recovery, producing copper cathode or gold doré on-site, thus eliminating the need for traditional milling and smelting processes. pH7 has previously commercialized its technology for extracting PGMs from spent catalysts and is positioned for further growth in the mining sector.
