Why is bauxite usually mined in open pits?

Bauxite is primarily mined in open pits because the vast majority of commercially viable deposits are located at or very near the Earth's surface.1

This geological positioning allows for efficient extraction with only minimal removal of the overburden—the soil and rock covering the ore. Because the deposits are accessible from the surface, mining operations can utilize methods such as blasting the beds loose and using power shovels or draglines to dig up the material for transport. This approach is the standard for surface mining when targeting minerals like bauxite, which serves as the principal ore for aluminum production.123
