Operations

Aluminum Corporation of China Limited (Chalco) operates across several major business segments, including alumina refining, primary aluminum smelting, mining, engineering and technical services, and international joint ventures.

Smelting

Domestically, Chalco commissioned a 400,000-tonne-per-year green aluminum smelter in Yunnan Province in early 2024, powered entirely by hydropower. The facility is part of China's decarbonization push and replaces older, coal-fired capacity.

Guinea

Chalco is also a member of the Chinese consortium participating in the development of the Simandou iron ore project, one of the world’s largest untapped high-grade iron ore deposits. Located in southeastern Guinea, the Simandou project is expected to supply over 100 million tonnes of iron ore annually once fully operational. The Chinese consortium includes Chalco and Rio Tinto who are jointly developing the infrastructure, including a 600 km railway and a deep-water port.
