KEYNOTE: In Process Tailings (IPT) Carbonation Technology: A Novel Approach to Mineral Carbon Storage

Stokreef, Arthur

Abstract

Mineral carbonation is a naturally occurring process that will contribute to the net zero transition through large-scale carbon capture and storage. The main challenge required to realize this opportunity is to speed up the process in an economically feasible way. Canada Nickel’s In Process Tailings (IPT) Carbonation technology is a novel approach to mineral carbon storage that is expected to create the largest CO₂ sink in Ontario, with a capacity to store more than 1 million tonnes per year of CO₂ at The Company’s Crawford Project. The Crawford Project is an ultramafic resource in Timmins, Ontario, that contains critical metals including Ni, Co, Pt, Pd, and Cr as well as these carbon sequestrating minerals. An overview of the IPT carbonation process and how this development could be used to offset pyrometallurgical emissions for zero carbon production of critical metals in Canada will be presented.
