flag Metallic Minerals Corp. successfully extracted 99.9% pure copper from ore using a new eco-friendly electrochemical method.

flag Metallic Minerals Corp. has achieved lab-scale success in extracting 99.9% pure copper from chalcopyrite-rich ore at its La Plata project in Colorado using a new electrochemical process. flag The method, developed with Columbia University, dissolves 70% of copper within four hours at ambient temperature without flotation or roasting, leveraging in-situ generated hydrogen peroxide. flag Copper is recovered via high-purity electrodeposition, while silver, rare earth elements, platinum group elements, and gold remain in a recoverable iron-rich residue. flag The system regenerates reagents, enabling a closed-loop, low-energy operation. flag The breakthrough could offer a smelting alternative, supporting domestic processing and value retention of critical minerals, with further research underway to recover elements in the residue and evaluate intellectual property protection.
