Bauxite mining in the Arkansas district specifically for aluminum production began in 1898. The district mined bauxite ore continuously until 1982; production varied through the years (Arkansas Geological Survey, 2018). Bauxite production increased in this district during World War II due to a government mandate to supply aluminum for airplanes.

Bauxite, the main ore for aluminium, is another bulk material that may contain trace but significant quantities of REE. Extraction of REE, including Sc, may be possible from bauxite as it is processed, or from red mud waste. Even though the concentrations of REE are low, given the large amounts of bauxite processed, production could be significant.
