SMM, May 27 –

According to SMM statistics, the total scale of alumina projects currently under construction or in the planning stage in Guinea has exceeded 11.4 million mt/year, with new capacity expected to be gradually commissioned after 2028.

From a project structure perspective, Chinese-invested enterprises remain the key driving force behind development. Many projects are integrated with supporting bauxite mines, captive power plants, and port facilities, highlighting a clear vertically integrated industrial chain strategy.

If these projects progress as planned, Guinea is expected to transform from a traditional bauxite-exporting country into a major global alumina production hub. This could have a profound impact on future global alumina trade flows and China’s long-term raw material supply security.
