Technology Extracting manganese with water
Our core differentiator is a proprietary, non-acidic process that replaces energy-intensive smelting. The process operates in a closed-loop system designed to minimize waste generation, eliminate acidic tailings, and reduce greenhouse gas emissions compared to conventional extraction and smelting methods.
Low-grade ores, mining and industrial tailings
Green Manganese Process
Metallized Manganese pellets
Revolutionising critical minerals recovery with technological leadership.
Recovery Rate
Our technology allows for a recovery rate of over 90% for manganese and other critical minerals from historic tailings and industrial waste.
Water-based manganese recovery
Proprietary process drastically minimises chemical use.
Same material - 80% reduced carbon footprint
A lower environmental impact alternative to raw material extraction, verified by an external lifecycle assessment (2025).
One process. Ten critical minerals.
Our process recovers other critical minerals present in the feedstock, among them cobalt, nickel, copper and zinc. Up to ten in total, depending on the source, all on the U.S. 2025 Critical Minerals List.
Product
End-to-end process confirmed
In 2026, Green Manganese produced Metallized Manganese pellets from manganese oxide made using the Green Manganese Process — confirming technical readiness from ore through to primary metal. The pellets contain more than 85% manganese with ultra-low impurity levels (P+S < 0.01%), meeting the specifications for modern steelmaking and manganese alloy production.
