Aluminium recycling - WikipediaAluminium recycling is the process by which scrap aluminium can be reused in products after its initial production. The process involves simply re-melting the metal, which is far less expensive and energy-intensive than creating new aluminium through the electrolysis of aluminium oxide (Al2O3), which must first be mined.cost and energy expenditure of aluminium extraction and recycling,cost and energy expenditure of aluminium extraction and recycling,Aluminium - Waste AuthorityAluminium. About aluminium. The primary source of aluminium is bauxite rock. Australia is the world's largest producer and exporter of aluminium, mining 40 per cent of . the recycling cost is much less than manufacturing . Recycling one aluminium can saves as much energy as it takes to run a television for three hours.
