pH7 Technologies, a company developing electrochemical extraction solutions for critical minerals, announced the final close of an oversubscribed Series B round, raising approximately $32 million in equity with support from new and existing investors, alongside venture debt financing bringing total funding to about $39 million.
Addressing Critical Mineral Supply Gaps
Rising global demand for metals such as copper is outpacing supply, driven by energy transition needs. Traditional extraction methods struggle to process low-grade ores and waste materials efficiently, creating a growing gap between demand and accessible resources.
“The constraint isn’t discovery, it’s how we process what we’ve already found,” said Mohammad Doostmohammadi, CEO of pH7 Technologies. “This oversubscribed financing validates that unlocking value from existing resources is now an economic and strategic priority. We are accelerating from pilot to commercial deployment globally, enabling producers to recover critical minerals from materials that were previously uneconomic — while enabling regionalized, on-site metal processing closer to the source of production.”
Scalable Extraction Technology
pH7’s closed-loop organo-electrochemical process enables recovery of metals from low-grade ores, tailings, and industrial waste. The system integrates with existing infrastructure, improving recovery rates while reducing energy use and environmental impact compared to traditional methods.
Commercialization and Expansion
Funding will support global deployment of the technology, starting with copper and expanding to nickel, gold, and platinum group metals. The company already operates a facility in Vancouver and is advancing large-scale applications in the mining sector.
