The aluminum industry involves the extraction, production, and processing of aluminum, a lightweight and durable metal. This industry plays a crucial role in various sectors, including construction, transportation, and packaging. The primary source of aluminum is bauxite ore, which is refined to produce alumina before being smelted into aluminum. Aluminum is valued for its resistance to corrosion and high strength-to-weight ratio. Major players in the aluminum industry include companies like Alcoa and Rio Tinto. The industry also focuses on sustainability, with efforts to recycle aluminum and reduce energy consumption during production.
