i think it's same as extracting other metals because it demands same types of chemicals and instruments.
in a differing opinion:
Aluminum is extracted from refined bauxite (alumina - Al2O3) through an electro-chemical process. It is extremely expensive to produce primary aluminum due to the large amounts of electricity required to break apart the aluminum molecules from the oxygen molecules and keep it from back reacting.
Recycling of aluminum is only about 5% of the cost of primary aluminum production in electrical energy.

The cost to extract aluminum varies depending on factors such as the location of the extraction site, energy costs, and extraction method used. However, on average, it can cost around $2000 to $2500 per ton to extract aluminum.
The costs of extracting aluminum or any metal is 70% to 95% of the current market value. Aluminium is selling at about $1500/tonne, then the cost of extracting it can be around $1200/tonne.
Advantages: Uses abundant raw materials, such as bauxite. Aluminum produced is high quality and recyclable. Can be used to extract pure aluminum from compounds. Disadvantages: Requires significant energy input, making it energy-intensive. Production process emits greenhouse gases. High initial investment cost for infrastructure.
The primary source of aluminum is bauxite, a rock that is typically found in tropical and subtropical regions. Bauxite is mined and processed to extract the aluminum mineral within it.
As of September 2021, the cost of aluminum is around $0.075 - $0.10 per gram. Prices can vary based on market fluctuations, demand, and supply conditions.
The cost of aluminum can vary widely depending on market conditions, but as of 2021, the average cost of aluminum is around $0.60 per 100 grams.
Aluminum was more expensive than gold when first discovered because it was difficult to extract pure aluminum from its ore using available technology at the time. This made the process of producing aluminum costly compared to gold. However, with advancements in technology, aluminum became easier and cheaper to produce, leading to a decrease in its cost over time.
