The document summarizes the process of extracting aluminium from bauxite ore. Bauxite ore is dissolved in cryolite to lower its melting point before being electrolyzed in a molten electrolyte. During electrolysis, positively charged aluminium ions move to the negatively charged carbon cathode, gaining electrons and forming aluminium atoms.
Aluminium is above carbon in the reactivity series and can therefore not be extracted with carbon. Impurities are removed from the bauxite ore at the start. Cryolite acts as a solvent and allows the electrolysis to take place at a lower temperature.
General Low in series occur native or extracted by roasting an ore e.g. Cu, Ag Middle of series metals below carbon are extracted by reduction e.g. Zn, Fe of the oxide with carbon or carbon monoxide High in series reactive metals are extracted using electrolysis e.g. Na, Al - an expensive method due to energy costs

Can Aluminium oxide be extracted using carbon? Aluminium is too high in the electrochemical series (reactivity series) to extract it from its ore using carbon reduction. The temperatures needed are too high to be economic. Instead, it is extracted by electrolysis. The aluminium oxide has too high a melting point to electrolyse on its own.

The extraction of bauxite through mining serves as the initial stage in the production process of aluminum. This process involves the extraction of the ore from the earth, followed by its processing to yield alumina. …
If there are people who want to wear gold anyway, or use it to fill cavities, or for micro-circuitry in computers and cell phones, that is all well and good but as someone proposed, take it from recycled sources. Of the 125,000 tons of gold extracted from the ground, more than 35,000 tons lie in the vaults of central reserve banks.
Aluminium is both an important input to a number of technologies critical to the energy transition and a major source of carbon emissions, responsible for around 3% of the world's direct industrial emissions in 2021, …
Supports nearly 700,000 direct, indirect and induced jobs and more than $228 billion in economic output. Committed or invested more than $10 billion in domestic manufacturing since 2013.
