Canada Nickel identifies a new method to accelerate CO2 capture
The lab-scale testing program demonstrates that this accelerated carbon capture process could allow the Crawford tailings to absorb enough CO2 to achieve net zero carbon emissions in 36 hours and generate up to 21 tonnes of CO2 credits per tonne of nickel produced in just six days, rather than the multiple months involved in existing passive tailings approaches. At Canada Nickel’s Crawford project, this translates to an average of approximately 710,000 tonnes of CO2 credits per year and 18 million tonnes of CO in total2 life-of-mine credits as part of the Preliminary Economic Assessment (“PEA”).
Marc SelbyPresident and CEO of Canada Nickel, said, “These lab-scale test results demonstrate a potentially transformative process for turning a nickel mine into a net carbon credit generator rather than a of carbon emissions. Our active, accelerated process has the potential to operate at least 8-12 times faster than current passive approaches, delivering carbon capture at a multiple of what industry leaders are currently capable of achieving. Our process also allows for easier quantification and verification of the amount of carbon captured.
Canada Nickel’s Crawford Project is hosted in ultramafic rock, which naturally absorbs and sequesters CO2. The potential for active carbon capture and sequestration was a key consideration in Canada The acquisition by Nickel of the 42 km2 target ultramafic rocks in the Timmins area that could anchor a zero-carbon industrial hub nearby Timmins. The challenge has been to develop a process that accelerates the natural carbon absorption process. Canada Nickel has developed a simple active process that uses the residues generated during the grinding process and injects a concentrated source of CO2 for a brief period of time. This new accelerated mineral carbonation process is called In Process Tailings Carbonation or IPT Carbonation, which fixes CO2 geologically while the tailings are still in the processing circuit, rather than after their final disposal.
Although Canada Nickel’s IPT carbonation process has only been demonstrated at the laboratory scale and on a limited number of samples, the Company believes that, given its relative simplicity, this process could be scale with the availability of concentrated (rather than atmospheric) sources of CO2. This CO2 could potentially be delivered through downstream processing of Crawford concentrates, a wide range of industrial processing activities, green hydrogen production, carbon capture facilities or natural gas power generation. The process clearly demonstrates the production potential of NetZero NickelMT and NetZero CobaltMT for the electric vehicle industry, NetZero IronMT and chromium for the stainless steel industry and generate substantial carbon credits in the process. The Company believes that the need for a concentrated source of CO2 for this process and the substantial CO2 the capture capability potential of its ultramafic terrestrial position could form the basis of an entire zero-carbon industrial cluster in the Timmins Region.
The IPT carbonation process uses tailings directly from the ore processing circuit and conditions it with CO2 for a brief period of time. After this conditioning, the tailings reached the Net Zero carbon capture target in less than 36 hours and achieved gross carbon capture rates of at least 26 tonnes of CO2 / ton of nickel (5 times the amount needed to achieve Net Zero metal production) in just 6 days. Meanwhile, the capture rate was 8-12 times faster than a lab-scale passive approach. (see figure 1a, 1b, 2, 3). Both samples tested with IPT Carbonation met or exceeded the theoretical full carbonation of the ultramafic mineral brucite, which is significant because the ability of brucite to sequester carbon, at Crawford alone, is estimated to be over 13 million tonnes of carbonation. CO2 over the estimated life of the project. The experimental method and results of IPT carbonation were initially completed at XPS, Expert Process Solutions, a Glencore company, and the mechanism was later replicated at a second independent laboratory, Kingston Process Metallurgy, adding confidence to the process. No further information is provided on the method at this time and work is underway to test a wide range of variables to optimize the process.
Based on mineralogical data entered into the Crawford PEA, the average brucite concentration of samples characterized in the resource was 2.0%. These first laboratory-scale results suggest that carbon capture beyond the theoretical maximum in brucite is possible. Canada Nickel is working to incorporate brucite content into the block model as an estimate of the project’s total carbon capture potential in the feasibility study.
Validation and measurement of CO2 Credits
IPT carbonation, which is an active process, has advantages over passive mineral carbon capture as a method of quantifying and verifying CO2 capture should be much simpler. Using a standard carbon footprint in the ore processing facility, CO2 captured by IPT Carbonation can be quantified before tailings are dumped into the permanent tailings storage facility, so carbon offsets can be quantified in real time as part of a standard metallurgical accounting system. Canada Nickel expects industry standards to be developed to quantify CO2 capture also by passive methods.
