pH7 has created an innovative process for extracting and refining critical metals, including Platinum Group Metals (PGM), that will enable the transition to renewable energy in an environmentally and economically sustainable way. Our disruptive closed-loop process applies organic, inorganic, and electrochemistry to reduce the environmental impact of the mining and recycling critical metals processes. This process enables efficient metal extraction, which is uneconomical or infeasible by current pyro or hydro metallurgy approaches, leaving high-quality metal products, including Platinum, Rhodium, Palladium, Copper, Nickel, Cobalt, etc. With no toxic emissions, wastewater, or effluent and lower energy consumption, pH7 partners with mines, OEMs, and recyclers seeking to minimize their environmental footprint and achieve their sustainability goals.
