On February 10, 2025, Rock Tech Lithium has been awarded a CAD$262,500 grant through Ontario’s Critical Minerals Innovation Fund. The funding supports a pilot project to evaluate crude tall oil, a by-product from the province’s pulp and paper industry, as a potential replacement for conventional chemical reagents in lithium mineral processing. This initiative could streamline domestic supply chains while cutting costs and environmental footprints in the growing battery materials sector.
The research focuses on the flotation stage, where lithium-bearing minerals are separated from waste rock. Currently, this process relies heavily on imported specialty chemicals, which add to operational expenses and logistical complexities. By testing crude tall oil—a material already generated in large quantities by Ontario’s forestry operations—Rock Tech aims to develop a locally sourced alternative. If successful, it could reduce dependency on foreign reagents and create a new revenue stream for pulp and paper mills, turning a low-value by-product into a high-demand industrial input.
This project aligns with broader efforts to strengthen North American critical mineral supply chains, particularly for lithium used in electric vehicle batteries and energy storage systems. Governments and industries are increasingly prioritizing secure, sustainable sourcing amid rising global demand. Rock Tech’s approach exemplifies how cross-sector collaboration—mining, forestry, and academia—can drive innovation. The company is partnering with Thunder Bay Pulp and Paper and researchers from Queen’s University to assess the commercial viability of crude tall oil in real-world applications.
From an environmental perspective, adopting forestry-derived reagents may lower carbon emissions associated with lithium processing. Traditional chemical production and transportation contribute significantly to the industry’s carbon footprint. Crude tall oil, as a renewable by-product, offers a circular economy solution that minimizes waste and promotes cleaner production methods. Rock Tech’s CEO, Mirco Wojnarowicz, emphasized that future competitiveness hinges not just on extraction but on advancing more efficient and eco-friendly processing technologies.
Exclusive insight from recent U.S. Department of Energy reports highlights a surge in domestic lithium demand, projected to grow over 300% by 2030 due to electric vehicle adoption. This context underscores the urgency for innovations like Rock Tech’s testing, which could set a precedent for similar initiatives in the United States. American mining firms are already exploring bio-based reagents to enhance sustainability, making this Ontario-funded project a relevant case study for cross-border technology transfer.
The collaboration also taps into regional expertise in Northwestern Ontario, known for its skilled workforce and rich natural resources. Kevin Holland, MPP for Thunder Bay-Atikokan, noted that such investments foster closer ties between mining and forestry sectors, spurring job creation and long-term economic growth. By integrating public funding with industrial and academic partners, the project aims to accelerate technology development while keeping economic benefits within local communities.
Charlotte Gibson of Queen’s University’s Critical Minerals Processing Lab added that this grant expands ongoing research into lithium processing optimizations. Her team will investigate how crude tall oil integrates into future project designs, potentially enabling more cost-effective operations at Rock Tech’s Georgia Lake lithium project. Earlier this year, the company reported promising results from an ore sorting program that could slash capital costs by up to 50%, indicating a pattern of incremental innovations aimed at improving project economics.
If crude tall oil proves effective, it could catalyze industrial diversification across Ontario and beyond. Forestry companies might supply processing materials to lithium miners, creating symbiotic relationships that enhance regional resilience. Rock Tech plans to incorporate findings into its broader strategy, including the proposed Red Rock Converter in Northwestern Ontario, which aims to establish a vertically integrated lithium supply chain from mine to market.
Ultimately, this initiative reflects a strategic shift toward domestic self-sufficiency in critical minerals. As governments worldwide ramp up electric vehicle manufacturing and energy storage deployments, innovations in processing efficiency become crucial. Rock Tech’s work could strengthen Canada’s position in the global battery ecosystem while offering scalable models for reducing emissions and fostering sustainable resource development.
