Supply Chain

Aluminum Supply Chain: From Mine to Market

The aluminum supply chain runs from bauxite mining (dominated by Australia, Guinea, and China) through alumina refining (China refines ~55% globally via the Bayer process) to primary smelting via the Hall-Heroult electrolytic process. China produces ~60% of primary aluminum but is approaching its 45 million tonne government capacity cap. Smelting is extremely energy-intensive at ~14,000 kWh per tonne, making electricity cost the primary determinant of competitiveness. Major trade flows run from Middle East and Russian smelters to European and Asian consumers. Secondary (recycled) aluminum requires only 5% of the energy of primary production and accounts for roughly one-third of global supply.

Production Geography

Global Aluminum production is led by China, which accounts for approximately 57% of world output, followed by India. The full list of major producing nations includes China, India, Russia, Canada, United Arab Emirates. This geographic concentration means that disruptions in key producing regions can have outsized impacts on global supply and pricing.

Extraction Methods

Aluminum is extracted using the following primary methods:

• Open-pit mining (bauxite)
• Strip mining

Processing and Intermediate Products

Aluminum is primarily sourced from Bauxite (gibbsite, boehmite, diaspore). After extraction, the raw material undergoes multiple processing steps including beneficiation, chemical treatment, and refining to reach the purity levels required by downstream industries. Typical ore grades range from 30-55% Al2O3.

Supply Chain Vulnerabilities

Key vulnerabilities in the Aluminum supply chain include concentration of 57% of production in China, limited processing capacity diversification, and long lead times for new mining projects. Monitoring these vulnerabilities remains important for supply chain resilience planning.
