Bauxite is a rock type that is used to produce metallurgical-grade alumina and chemical-grade alumina/aluminum hydroxide using the Bayer process . During this process, the finely ground bauxite ore is digested under pressure in a strong caustic (sodium hydroxide) solution at temperatures ranging from 100 to 260 °C.
