    Aluminium is the most abundant metal on Earth. However, it is expensive because a lot of electricity is used to extract it. Bauxite is the aluminium ore. It is purified to yield aluminium oxide, which is a white powder. Aluminium is then extracted from aluminium oxide by electrolysis. The aluminium oxide must be made molten so that the ions can

    Extraction of Metals. Industries extract metals from their ores. What are ores? Let me explain in a simple way. Usually, less reactive metals such as gold and silver are found in their pure form in the soil. But this is not the case with more reactive iron or aluminum. Usually iron and aluminum exist as compounds, with oxygen, also known as oxides
