Hard rock, easy lithium.

Big Picture

Lithium deposits come in two flavors: mineral-rich waters called “brines” and solid ore deposits called “hard rock.” The latter accounts for about 40% of global reserves. But tapping hard rock for battery-grade lithium requires massive infrastructure projects that are slow and costly to build and operate. The strong acids used for leaching wreak lasting damage on ecosystems and are a killer to new site permitting.

How it Works

Novalith’s patented process selectively extracts lithium from hard and soft rock using  CO2 instead of strong acids. The process avoids the environmental toll of leaching while sequestering two tons of CO2 per ton of lithium extracted. The chemistry is highly selective, yielding 99.8% pure lithium carbonate, enabling cost-effective recovery of lithium from mine tailings and battery waste.

Unfair Advantage

Novalith’s process cuts process costs, plant costs, and plant footprints by 65%, 50%, and 25%, respectively. The carbon-negative process eliminates waste, harmful tailings, and 90% of water use, making tricky site permitting a breeze. On top of that, cost-effective hard rock extraction unlocks huge yet untapped lithium resources in a wide range of geographies as mineral supply chains grow more geopolitically strategic.
