How Aluminium Is Produced

The aluminium production process is much more complex and requires huge amounts of electricity. For this reason aluminium smelters are always built in the vicinity of power energy sources usually hydroelectric power plants that dont contaminate the environment. But lets start at the beginning

Global Aluminium Smelters Production Costs On

Production costs for smelters are highly dependent on the global economic environment which affects oil prices and the prices of other commodities including those that create smelters input costs. For instance during the global economic crisis in 2009 production costs for aluminium smelters decreased between 30 and 40 compared to the record high costs Continuar leyendo 187;

Aluminum Production

32.6 Aluminium 32.6.1 Production of aluminium. Aluminium production is energy intensive. About 17000 kWh of electricity are required to produce 1 tonne of aluminium. This means that it has a relatively high cost. However it is very suitable for recycling. It is rarely used in its pure form

Energy Needed To Produce Aluminum

Aluminum production in the United States generally takes two forms with very different energy requirements. Primary production involves making aluminum products from raw material or ingots which is highly energy intensive especially electricity intensive
