Bauxite

Bauxite

Overview

Bauxite is usually strip mined because it is almost always found near the surface of the terrain, with little or no overburden. As of 2010 , approximately 70% to 80% of the world's dry bauxite production is processed first into alumina and then into aluminium by electrolysis. Bauxite rocks are typically classified according to their intended commercial application metallurgical, abrasive, cement, chemical, and refractory.
Usually, bauxite ore is heated in a pressure vessel along with a sodium hydroxide
