The metals are collected and then melted at high temperature. They then have any impurities scraped off the top of the container of molten metal. The pure molten metal is then poured into casts and cooled. The blocks of metal can now be used again. It is cheaper and less environmentally damaging to recycle metals rather than extract them from their ores, in the ground.

∙ 12y agoEven though aluminum and iron are the third and fourth most abundant elements in Earth's crust, the amount of energy used in refining and smelting aluminum and iron or steel is higher than the amount of energy used in reprocessing used metal products such as cans and other sorts of scrap metal. Carbon dioxide emissions and the use of clean water are also less in reprocessing previously refined metals.

Can Aluminium can be recycled this makes it a sustainable material?
Aluminium is the worlds most abundant metallic element in the earths crust, and can be recycled without degradation of properties though some is lost. Aluminium's high scrap value and well established recycling infrastructure make it the most frequently recycled metal, so much that 73% of the aluminium ever produced is still in use today. Recycling is not a perfect process and ultimately it will be all used.
