Supplier companies

5 companies produce manganese sulfate (battery grade).

CITIC Dameng Mining Industries(1091.HK)

HQ CN10% share

Chinese manganese miner/processor; ferromanganese, EMM and high-purity manganese sulfate (HPMSM) for batteries.

Euro Manganese Inc.(EMN.AX)

HQ CA0% share

Developing high-purity manganese (HPMSM/HPEMM) production in Czechia (Chvaletice tailings) — a non-China battery-manganese source.

Eramet / Comilog (Gabon Manganese)

HQ FR

French mining conglomerate (Euronext: ERA, HQ Paris); through Comilog subsidiary operates world's 2nd largest manganese ore mine in Moanda, Gabon (producing >70% of Gabon's ~10M tonne annual output; Gabon is world's 2nd largest manganese producer). High-grade ore: 45-50% manganese. CRITICAL FUTURE DISRUPTION: Gabon government issued ban on export of unrefined manganese ore effective January 1, 2029 — forcing Eramet to process locally or exit the market. Eramet is simultaneously negotiating with the Gabonese government while building local processing capacity. Same Eramet also produces nickel (New Caledonia) and lithium (Argentina).

Guizhou Redstar Developing

HQ CN
