Bauxite - Sandatlas

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.
