underground miners to data scientists, we want your hard work, dedication and outside-the-box thinking Home Products -- Products Lightweight and infinitely recyclable, aluminium is found in everything from jet engines to electric vehicles to mobile phones. It is the most abundant metal in the Earth’s crust, and one of the world’s fastest growing major metals. But we are only scratching the surface of the opportunities for aluminium to be a part of our everyday lives. For example, analysts predict the use of aluminium in lightweight cars and trucks in North America will increase by about 30% – from 177 kilograms per vehicle in 2015 to 227 kilograms in 2025. According to the Stewardship Initiative (ASI), for every 10% reduction in the weight of a vehicle, fuel economy increases by about 7%. Over its lifetime, every kilogram of aluminium that replaces heavier materials in a car or light truck can save a net 20 kilograms of carbon dioxide emissions. is made from bauxite, or aluminium ore. Bauxite is the basic raw material that is refined into alumina, which in turn is sent to smelters for processing into aluminium. First discovered near Les Beaux in the South of France in 1821, bauxite was initially called “beauxite”. In 1886, Charles Martin Hall and Paul Héroult independently developed a process for making aluminium from alumina. And in 1887, Austrian scientist Karl Josef Bayer patented his self-titled process for extracting alumina from bauxite. Today, the Bayer process and the Hall-Héroult process are still combined to process bauxite ore into alumina, and t...
