Summary

The opportunity titled 'Electrochemical Arsenic Immobilization for Sustainable Cobalt Production' focuses on an innovative electrochemical method designed to extract cobalt from sulfoarsenide minerals, particularly cobaltite, while simultaneously immobilizing arsenic in a stable form. This dual approach addresses the challenges of cobalt extraction from arsenic-rich sources, which have been largely untapped due to environmental and safety concerns. The work involves developing a scalable and energy-efficient process that operates under moderate temperatures and ambient pressure, eliminating the need for hazardous chemicals and high-pressure systems. Contractors with expertise in electrochemical processes, mineral processing, and environmental remediation are encouraged to bid on this opportunity, particularly those capable of commercializing the technology for sustainable cobalt production.
Description

Technology Summary

This technology introduces an electrochemical method for extracting cobalt from sulfoarsenide minerals, such as cobaltite (CoAsS), while simultaneously immobilizing arsenic as scorodite (FeAsO₄·2H₂O), a stable and low-solubility mineral form. The
