After the bauxite is mined, it is refined into alumina before it is ready to be reduced to primary aluminium. At the smelter, the alumina – now a powder – goes through the Hall–Héroult electrochemical process to convert it into aluminium metal. Let’s take a look at by far the most common method of obtaining […]
