Its role Owner
South32 Limited is a globally diversified mining and metals company headquartered in Perth, Western Australia. Spun out from BHP Billiton in 2015, it is listed on the Australian Securities Exchange (ASX: S32) with secondary listings in Johannesburg and London.
The company produces commodities including bauxite, alumina, aluminium, manganese, copper, nickel, silver, lead, zinc, and metallurgical coal. It operates nine assets across six countries in Australia, Southern Africa, South America, and the Americas, such as the Worsley Alumina refinery and bauxite mine in Australia, aluminium smelters in South Africa, Mozambique, and Brazil, and manganese operations in Australia and South Africa.
South32 focuses on minerals critical to the energy transition, with around 8,900 employees and FY25 underlying EBITDA of US$1.9 billion. While primarily a mining firm, its alumina production—refined from bauxite—links to the chemical industry as a key feedstock for aluminium.
