pH7 Technologies is a cleantech company based in Vancouver, BC, developing a proprietary closed-loop process to extract critical and precious metals in a more sustainable and economical way. Using a combination of organic, inorganic, and electrochemical methods, our process enables the recovery of high-value metals—including Platinum Group Metals (PGMs), gold, copper, nickel, and cobalt—from challenging sources such as mine tailings, low-grade ores, waste rock, and end-of-life materials. Unlike traditional extraction methods, pH7’s process produces no toxic emissions or wastewater and significantly reduces energy use and greenhouse gas emissions, including a 99.9% reduction in SOx, NOx, and CO₂. By working with mining companies, OEMs, and recyclers, we help reduce environmental impact, improve metal recovery efficiency, and support the transition to renewable energy and a low-carbon, circular economy.
