Answer (1 of 1): The Cost and energy expenditure involved in the extraction of aluminum from its ore is far bigger than the energy required to recycle aluminium The percentage of energy required to recycle aluminum is appoximately 5% of the energy it takes to extract aluminum from its ore More information can be found online comparing the costs in a graph this may help a bit ...
You need a lot energy to melt the metal compound and then you'd need a great deal of electrical energy to extract the metal from the molten compound. Metabolic processes that require oxygen are ...
Aluminium is an "energy bank"; most of the original input can be recovered every time the product is recycled. Bauxite mining requires relatively low energy inputs, compared to other steps in the aluminium production process – with less than kilograms of fuel oil (mainly in the form of diesel for haul trucks) and less than 5 kWh of electricity consumed per tonne of bauxite extracted.
