Electrochemical Arsenic Immobilization for Sustainable Cobalt Production

a stable and low-solubility mineral form. The process enables cobalt production from arsenic-rich domestic sources by addressing both metal recovery and arsenic stabilization in a single system. The method operates at moderate temperatures (up to 70�C) and under ambient pressure conditions, without

the need for chemical oxidants or high-pressure equipment. Challenge Domestic sources of cobalt remain largely untapped due to the presence of arsenic, which complicates extraction and disposal. Existing approaches to arsenic immobilization
