Africa re[de]fined
Sustainable Battery-Grade Manganese
Battery-grade manganese is a vital raw material for rechargeable lithium-ion batteries used in electric vehicles (BEVs and PHEVs) and energy storage systems (BESS) – essential to the Green Energy Transition. Despite its significance, global supply chains of battery-grade manganese remain severely restricted.
Manganese ore is abundant and mined in vast quantities, mostly for use in steel manufacturing. Only a tiny fraction is used in the production of high-value, high-purity manganese products.
Green Metals Refining (GMR) is a midstream refining company dedicated to the production of sustainable, low-cost, battery-grade manganese chemicals from African raw materials.
Our Flagship Project
GMR’s flagship project is a manganese refinery in Walvis Bay, Namibia.
It will process ore from South Africa into battery-grade manganese for consumption by global battery manufacturers.
A co-located captive sulphuric acid plant will reduce refinery production costs and sales to third parties will help stimulate Namibian industrial development. Namibia is currently a net importer of acid.
