Annual production of aluminium foil was approximately 850,000 tonnes (940,000 tons) in Europe in 2014, [1] and 600,000 tonnes (660,000 tons) in the U.S. in 2003. [2] Approximately 75% of aluminium foil is used for packaging of foods , cosmetics , and chemical products, and 25% is used for industrial applications (e.g., thermal insulation ...
There is a wide variation of price of carbon depending on its form. Lower ranks of coal can be less expensive, for example sub-bituminous coalcan cost around US$0.038/kg carbon.[19] Graphiteflakes can cost around US$0.9/kg carbon.[20]

Cathodes are made of anthracite; high purity for them is not required because impurities leach only very slowly. The cathode is consumed at a rate of 0.02–0.04 kg per each kilogram of produced aluminium.
