The energy to recycle materials into new products is most often expressed as the ratio between the energy cost to recycle the product and the energy to make products from virgin materials. Recycling aluminum uses 95 percent less energy than extracting aluminum from bauxite ore.
2017-03-27· Extraction of Metals. Extraction of Aluminium.. Aluminium ore is called bauxite. Bauxite contains aluminium oxide, water, iron oxide and other impurities. The purified dry ore, called alumina, is aluminium oxide Al 2 O 3.. The alumina must be molten for electrolysis to work, since the ions are not free to move in the solid state. Unfortunately, alumina has a high melting point (2040 °C)
