Tailings dam failures can cause devastation to the environment, loss of human life, and require expensive remediation. A promising approach for de-risking brucite-bearing ultramafic tailings is in situ cementation via carbon dioxide (CO2) mineralization, which also sequesters this greenhouse gas within carbonate minerals. In cylindrical test experiments, brucite [Mg(OH)2] carbonation was accelerated by coupling organic inorganic cycling. Waste organics generated CO2 concentrations similar...

<p>Ultramafic (Mg-rich) mine wastes are produced in vast quantities, of no economic value, and their storage impoundments can be susceptible to catastrophic failure.<sup>1</sup> Carbon dioxide (CO<sub>2</sub>) mineralization these form carbonate cement reduce greenhouse gas emissions<sup>2</sup> assist de-risking through physical stabilization.<sup>3</sup>...
