Mining Bauxite By Nigel Burch Posted on April 7, 2013 Bauxite is aluminium ore. It is formed over millions of years by the breakdown of iron-poor volcanic rocks that are exposed to high-rainfall weathering. It becomes of economic interest when the alumina (aluminium oxide) content has risen to at least a third by weight.
