Processing and Refining Bauxite Ore. Once the bauxite ore is extracted, it's not ready to become your next soda can just yet. The ore goes through a series of processes to extract the valuable aluminum oxide it contains. This refining process involves crushing the bauxite ore, mixing it with caustic soda, and then heating it in a pressure vessel.
