Essay on Bauxite: Formation, Uses and Production

2021-6-28  Australia is the undisputed leader of bauxite production, contributing more than one-third of global production each year. It has been estimated that Australia accounts for about two-fifth of the global bauxite reserve. The largest bauxite reserve of Australia and the world is Weipa in Cape York Peninsula. The layers of bauxite are, on an average, 5 meter thick and situated very near the surface. The open cast mining method enabled it to mine bauxite
