Aluminium is found on Earth primarily in rocks in the crust, where it is the third-most abundant element, after oxygen and silicon, rather than in the mantle, and virtually never as the free metal. It is obtained industrially by mining bauxite , a sedimentary rock rich in aluminium minerals.
Before the early 1800s, aluminum had not been produced as an isolated metal. It wasn't until 1825 that; Hans Christian Ørsted discovered how to create elemental aluminum via the reduction of aluminum chloride. Since aluminum is a light element with good mechanical properties, it was widely sought to replace heavier less functional metals like ...
At the same time, liquid aluminum was deposited at the cathode. Marsh and Hoskins' method was not only more efficient than previous processes, but also enabled the production of high-purity aluminum. This aluminum found a wide range of applications, from the aviation industry to electrical cables and packaging materials. [6]
