Vancouver’s Rockburst Technologies is redefining what’s possible in the mining sector by introducing climate-focused innovation to one of the industry’s most energy-intensive stages: comminution, the crushing and grinding of rocks to extract valuable minerals. Founded in 2020, Rockburst is on a mission to address the substantial energy consumption and carbon emissions associated with mineral processing—a process responsible for up to 4% of global electricity use.
At the core of Rockburst’s breakthrough is its patented CoreBurst™ technology. Rather than relying on conventional compression, CoreBurst™ uses supercritical CO₂ to fracture rocks from within. This approach not only slashes energy requirements—early tests show up to 50% savings for certain ores—but also eliminates the need for large volumes of water, and may even facilitate carbon sequestration as part of the process.
Rockburst’s journey from concept to a TRL 5 “Beta” system has been fueled by approximately $5 million in non-dilutive funding from organizations such as Natural Resources Canada, Innovate BC, and the government of South Australia. Strategic partnerships with leading institutions like UBC, BHP, and Anglo American have further accelerated development. The company is now raising an additional USD $5.2 million to build its first on-site pilot unit.
Through its CoreBurst™ as a Service program, Rockburst is already working with early adopters to test ore samples and validate its technology in real-world conditions. This collaborative approach is driving continuous improvement and supporting the industry’s transition to more sustainable practices.
Being headquartered in British Columbia has provided Rockburst with access to a vibrant cleantech ecosystem and mining expertise, enabling the company to attract top talent and secure critical funding. As a finalist for the BC Tech Company of the Year – Startup award, Rockburst’s recognition highlights the growing importance of innovation in even the most traditional industries.
Rockburst Technologies is proving that mining can be a catalyst for the clean energy transition, delivering solutions that reduce emissions, conserve resources, and pave the way for a more sustainable future.
