Nornickel investigating using mining tailings to capture and store CO2

Green Car Congress

Ore mining and concentration results in waste rock, or tailings—fine-grained rock (less than 0.4 As a waste, tailings are stored in designated storage facilities called tailing dams. Silica and magnesium oxide contained in waste rock can absorb carbon dioxide during weathering (long-term exposure to air).
