Bauxite an overview ScienceDirect Topics

Since bauxite occurs naturally at the surface of the Earth’s crust, mining practices tend to be straightforward. Surface pits are opened using explosives to reveal bauxite beds. The bauxite ore is then excavated and loaded into trucks or rail cars for transportation to the converting or processing centre.
