Manganese Metal Company

What Manganese Metal Company does

Manganese Metal Company (Pty) Ltd (MMC) refines electrolytic manganese metal (EMM) at its Mbombela (Nelspruit) facility in Mpumalanga, South Africa, where it has operated continuously since 1974. The company is the world's only non-China based producer of high-grade EMM and the world's largest refinery of 99.9% selenium-free EMM, using a proprietary SO2-based electrolytic process (rather than selenium dioxide) that delivers higher purity (99.9% vs 99.7%), eliminates hazardous hydrogen selenide emissions, and supports a portfolio of grade-specific products: Low Hydrogen Flake (LH), Low Oxygen Flake (LO), Stabilised Powder (SP-60), Unstabilised Powder (UP-40), and Manganese Aluminium Briquettes (75% and 85%). MMC sells primarily to enterprise customers across steel, aluminium, welding consumables, specialty alloys, and lithium-ion battery pCAM (precursor cathode active material) end-markets, with approximately 95% of production exported to more than 120 customers in 20 countries and Japan alone accounting for more than one-third of total output. Distribution is handled through direct sales (Sales Manager Imraan Khan), an in-house logistics team, strategically placed warehouse stock in key markets, and a Tokyo-based MMC Japan Office operated via local partner Msz & Company.

MMC is privately held by Manganese Metals Holdings (Pty) Ltd, which consolidated sole ownership in March 2013 after acquiring Valmont's remaining 49% stake. The company is transitioning from a single-product (EMM) industrial minerals refiner to a vertically integrated battery materials supplier. In 2026 it is commissioning the MTX-1 plant, a 6,000-tonne-per-annum High Purity Manganese Sulphate Monohydrate (HP MSM) facility that converts EMM flakes into battery-grade manganese sulphate crystals using 100% renewable electricity; production of qualification volumes is expected in H2 2026, with planned scale-up to 30,000 tpa in the near term and an Ore-to-Crystal (OTX) process targeting an additional ~30,000 tpa beyond 2030. Revenue mechanics are quote-based, negotiated under multi-year contracts and MMC's standard Terms of Sale; pricing is not publicly disclosed. The company holds ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and REACH certifications, and has pursued infrastructure partnerships (Manganese Producers' Consortium for the Ngqura port terminal), workforce development (EU Global Gateway/CSIR/EWSETA), and operational upgrades (ABB AC 800PEC/MCR1000 power systems) to support scaling.
