At the processing plant, the bauxite is heated hot

Question: At the processing plant, the bauxite is heated hot enough to melt the rock. Electricity is applied to the melted rock to separate out pure aluminum in its liquid state. The leftover material, called slag, is broken up, forming large amounts of what is basically burnt rock, which is caustic and reactive.

Aluminium, Alumina and Bauxite

Mined bauxite ore is refined into alumina through what is known as the Bayer process. The process, discovered in 1887, extracts alumina from bauxite through crushing, dissolving it in caustic soda, filtration and an electrolytic process. Alumina is a white powder, appearing similar to table salt, which can then be smelted into aluminium metal.
