Notes
Only primary magnesium producer in the Southern Hemisphere and the only fully integrated dolomite-to-die-casting magnesium plant identified. USGS puts 2024 output at 20 kt against 22 kt/yr capacity; a 2009 UNFCCC CDM project document for the site (Bocaiúva, Minas Gerais) records 26,000 t/yr of ingot and liquid-metal furnace capacity plus ~7,500 t/yr primary ingot casting and ~10,500 t/yr die casting, so older nameplate figures differ from current USGS capacity. Products stated: magnesium metal; magnesium alloys; die-cast magnesium components; silicon metal
