Problem
Traditional manganese extraction relies on acid-based processes that generate large volumes of hazardous waste, emit significant greenhouse gases, and consume high amounts of energy. These environmental and cost challenges limit the use of low‑grade ores and tailings, constraining supply for battery and green‑steel manufacturers.
Solution
Green Manganese employs a water‑based, closed‑loop extraction method that replaces acids with recyclable chlorides, dramatically reducing waste and emissions by up to 80 %. The process recovers high‑purity manganese from low‑grade ores and tailings while using 6–10 × less energy than conventional methods. Reagent recycling and efficient heat integration keep production costs competitive, enabling affordable supply of manganese for battery cathodes and steel alloying. By locating facilities near North American and European feedstocks, the technology strengthens regional supply chains and reduces reliance on distant, carbon‑intensive sources. The approach is validated at bench scale and is ready for pilot‑scale continuous operation.
Target Audience
Primary customers are battery manufacturers, steel producers, and industrial material suppliers seeking sustainable, cost‑effective manganese inputs, as well as downstream OEMs focused on decarbonizing their supply chains.
