Sustainable Bauxite Mining Guidelines

Sustainable Bauxite Mining Guidelines ii Executive summary . Bauxite, the primary ore used to make aluminium, is refined into alumina, which is then smelted into aluminium. Other uses of alumina include stone grade applications. Bauxite demand has historically been met by a few large players in the market, which have operated large scale mines.

Bauxite Mining and Alumina Refining - PubMed Central (PMC)

May 08, 2014 · Exposures to bauxite dust, alumina dust, and caustic mist in contemporary best-practice bauxite mining and alumina refining operations have not been demonstrated to be associated with clinically significant decrements in lung function. Exposures to bauxite dust and alumina dust at such operations are also not associated with the incidence of cancer.
