Oct 21, 2020 Bauxite Uses. The term bauxite is used for naturally occurring mixtures of aluminum monohydrate. The bauxite used by the chemical and refractory industries in the United States in 1959 amounted to about 320,000 long dry tons. Bauxite is used mainly as an ore of aluminum and as raw material for the manufacture of aluminum chemicals.
Bauxite is a result of intense leaching in a hot and humid climate with alternating wet and dry seasons and good downward drainage. The climate promotes vegetation that provides organic acids, which help to dissolve rocks in percolating water that carries more soluble components away, leaving only aluminum and also often iron as the least mobile common ions behind.
