Renforth Resources and Queen's University test nickel recovery with carbon capture at Victoria deposit

Renforth Resources is testing a hydrometallurgical process with Queen's University that could recover nickel, cobalt, copper and zinc from pyrrhotite at its Victoria deposit in Quebec while also capturing CO2 through mineral carbonation. The work includes bench-scale leaching, column tests that simulate heap leaching, and a techno-economic analysis plus life cycle assessment. The Victoria deposit is large, with an inferred resource of 125 million tonnes containing 331 million pounds of nickel and 28 million pounds of cobalt. If the process works at scale, it could give battery and EV supply chains a way to source metals with a smaller carbon footprint. The results from the column tests and the LCA will determine whether the approach is viable beyond the lab.

Interesting pairing. Heap leaching pyrrhotite for nickel/cobalt while carbonating the host rock could address two problems at once. The Victoria resource is large, but the key is whether the leach kinetics and reagent costs work at scale. Bench and column tests should give a clearer answer.

The carbon capture part is worth watching because it is mineral carbonation, not CCS with storage liability. If CO2 reacts with magnesium and iron minerals to form carbonates, it is permanent. But the life cycle assessment matters more than the press release. Need to see energy and reagent inputs.

Column leach tests on coarse material are the right first step, but heap leaching is slow and weather dependent. For a deposit in Quebec, winter conditions could stall operations for months. Also curious about water management and acid/base balance at neutral to weakly alkaline pH.

The interesting policy angle is whether the carbonated tailings can be counted as verified CO2 removal. If they want credit or scope 3 benefit, they will need measurement and monitoring protocols, not just lab results. The IP agreement with Queen's could also affect future licensing.

Not my usual area, but the metallurgy is relevant to low-carbon supply chains. Battery makers are under pressure to prove lower embedded emissions. If this process recovers metals that flotation misses and stores CO2 at the same time, it could shift the economics for ultramafic ores. Payback depends on reagent and energy costs.
