Carbon negative mines: mineral carbonation of mine waste (2026)

Abstract

This study proposes mineral carbonation of AMD for neutralising acidity and sequestering CO2 in gold and copper mine wastes in Western Australia. We propose to convert these mine waste into inert carbonate minerals using alkaline brine lixiviants, thereby facilitating efficient CO2 storage.
