WebAug 25, 2024 · Examination of the Ellingham diagram shown above illustrates why the metals known to the ancients were mainly those such as copper and lead, which can be obtained by smelting at the relatively low temperatures that were obtainable by the methods available at the time in which a charcoal fire supplied both the heat and the carbon. Webformed from synthetic sodium aluminium fluoride, which means the process uses less energy. The process does still require a huge amount of energy as the solution must be heated to well over 750°C so that the molten aluminium can be removed.
