Extracting Manganese with Water

At Green Manganese, we transform untapped resources like low-grade ores and tailings into high-value, critical manganese products, strengthening resilient value chains across North America and Europe.
By delivering affordable, sustainable manganese for batteries and green steel, Green Manganese supports both the energy and industrial transition.

Revolutionising manganese production with technological leadership.

Modern and clean extraction

Green Manganese uses a water-based, closed-loop process replacing acids with chlorides, cutting waste and emissions by up to 80 percent.

Access to new and untapped resources

Our technology turns low-grade ores, tailings, and smelter dust into new domestic manganese sources for North America and Europe.

Affordable Manganese production

We produce high-purity manganese at competitive market prices through efficient processing, reagent recycling, and 6–10× lower energy use.

Supply chain security

Using local resources and locally designed technology, we strengthen North American and European supply chains for clean, resilient manufacturing.

OUR TECHNOLOGY

Bench-Scale Results: Proven Performance.

Green Manganese’s process has been validated through extensive bench-scale testing at the University of British Columbia’s Department of Materials Engineering.

OUR RESULTS

The results confirm that our water-based, closed-loop extraction technology performs efficiently across multiple feedstocks and can be scaled to continuous pilot operations.

This study demonstrates not only strong manganese recovery but also the potential to recover other critical elements — a key step toward full-scale deployment.
