Arsenic-rich mining & processing wastes
Investigate arsenic-bearing mining and processing wastes and develop pathways toward recovered materials.
A distinct legacy-waste challenge
Mining, ore roasting, and mineral processing can generate concentrated arsenic-bearing wastes. We investigate their chemical forms and reactivity to develop recovery routes suited to these materials.
Identify reactive arsenic phases
Understand the speciation and dissolution behavior of arsenic in mining and processing residues.
Develop recovery pathways
Connect extraction and chemical transformation with the production of elemental arsenic.
Explore material applications
Investigate pathways from recovered arsenic to useful materials, including potential semiconductor applications.
The scientific approach
Speciation and recovery
Laboratory experiments are combined with synchrotron X-ray characterization to understand the reactions and solids that control recovery.
