Abstract

Alumina is produced by refining bauxite, which is stripped from open cut mines; aluminium, one of the world’s most important lightweight metals used in packaging, transportation and construction, is in turn produced by smelting alumina. About 259 million tonne of bauxite is mined annually throughout the world from a global
reserve of 55-75 billion tonnes, with 30% of bauxite mined in Australia (77 mt), 18% in China (47 mt), 13% in Brazil (34 mt), and 7% in India (19 mt), with the remainder
mined in countries such as Guinea, Jamaica, Indonesia, Malaysia and Russia. A byproduct of alumina production is bauxite residue, also called red mud, a hazardous waste produced at about 120 million tonnes per year. This article considers a sustainable reuse model for red mud.
