Canada Nickel releases carbon storage testing results

Canada Nickel reveals that its In-Process Tailings (IPT) Carbonation approach has the ability to store 1Mt of carbon dioxide annually when the project is scaled up.

Canada Nickel’s Crawford Nickel-Cobalt-Sulphide Project is hosted in ultramafic rock, which naturally absorbs and sequesters CO₂. The IPT Carbonation process involves injecting a concentrated source of CO₂ into tailings generated by the milling process for a brief period of time.

This captures carbon geologically in the tailings while they are still in the processing circuit, rather than after they have been finally deposited.

In the current phase of test work, Canada Nickel has conducted a series of variability tests to establish the IPT Carbonation process engineering design criteria and develop predictive CO₂ storage models.

Testing was done on samples based on their brucite content as well as their location within the deposit, with a bias towards material that is expected to be processed in the initial project phases.

IPT Carbonation has been incoporated into the integrated feasibility study for the project, which is due to be delivered this September.
