Prospects for CO2 mineralization and enhanced weathering of ultramafic mine tailings from the Baptiste nickel deposit in British Columbia, Canada

Ian M.Power, Gregory M.Dipple, Peter M.D.Bradshaw, Anna L.Harrison Abstract The Baptiste deposit is located within the Decar nickel district in British Columbia, Canada and is a promising candidate for a CO2 sequestration demonstration project. The deposit contains awaruite (nickel-iron alloy) hosted in an ultramafic complex, which is dominated by serpentine [Mg3Si2O5(OH)4; ∼80 wt.%] and contains reactive brucite [Mg(OH)2; 0.6–12.6 wt.%]. Experiments were conducted using metallurgical test samples and pulps from cores with the aim of determining the potential for this deposit to sequester CO2 via direct air capture of atmospheric CO2 and ...
