Guinea Implements Bauxite Export Controls to Boost Global Prices; Chinese Aluminum Industry Faces Supply Shock

African Mining News (May 27): According to Bloomberg, Bouna Sylla, Guinea’s Minister of Mines and Geology, officially announced on May 25 that the country would implement bauxite export controls starting in June. The primary objective is to bring global bauxite prices back to reasonable levels by limiting total export volumes. This move marks another instance of resource nationalism by a major African resource-rich nation, following similar restrictions on cobalt exports by the Democratic Republic of the Congo and lithium exports by Zimbabwe.

Sylla stated that Guinea's bauxite exports surged by 25% year-on-year to 183 million tonnes in 2025. This oversupply caused global bauxite prices to plummet from $120 per tonne in early 2025 to less than $60 per tonne by the beginning of this year, severely impacting both mining company profits and government revenue.
"Supply cannot exceed demand; we aim to return prices to a reasonable range by regulating export volumes." He revealed that the government plans to cap total bauxite exports for 2026 at 150 million tonnes—a reduction of 33 million tonnes, or 18%, from the actual export volume in 2025.
In addition to volume caps, Guinea has introduced a series of supporting measures: raising bauxite export tariffs from 5.5% to 10%; mandating that 50% of exports be transported by the state-owned shipping company; launching an official "Guinea Bauxite Index" as a pricing benchmark; and directly linking export quotas to commitments by mining companies to build local alumina refineries. Companies that fail to honor their refinery construction pledges face cuts to their export quotas or even the revocation of their mining licenses.
This news immediately sent shockwaves through China's aluminum industry. The main alumina futures contract on the Shanghai Futures Exchange surged as much as 4.3% intraday to 2,865 yuan per tonne, reversing its year-to-date trend from a decline to a gain. Peng Dinggui, an analyst at Zhongtai Futures, stated that if the 150-million-tonne export cap is implemented, the global bauxite market will shift from a surplus to a state of significant tightness; this would sharply drive up bauxite prices and accelerate the phase-out of high-cost alumina production capacity within China.
Data shows that China is the world's largest aluminum producer; in 2025, it imported 201 million tonnes of bauxite, with 75% originating from Guinea. In March of this year, Guinea's monthly bauxite exports to China hit a record high of 18 million tonnes.

To cope with export controls, Chinese companies have accelerated the construction of alumina refineries in Guinea. Consortia led by SPIC (State Power Investment Corporation), Chinalco, and Singapore's Winning International Group are currently building three alumina refineries there, with a combined capacity set to reach 7.2 million tonnes.
The Guinean government has stated that its goal is to have five alumina refineries operational by 2030 and eventually introduce electrolytic aluminum production capacity, thereby transforming the country from a raw material exporter into an aluminum processing nation.
