IntroductionBauxite residue has been continuously produced since the development of the alumina/aluminium industry in the late nineteenth century -and the global inventory is estimated to be around 3,000 million tonnes at the end of 2010 1 Klauber, C., Grafe, M., and Power, G, 2009 -and growing at approximately 120 million tonnes per annum. This makes,Red mud - Wikipedia,Red mud, preferably known as bauxite residue, is an industrial waste generated during the processing of bauxite into alumina using the Bayer process. It is composed of various oxidecompounds, including the iron oxides which give its red colour. Over 95% of the alumina produced globally is through the Bayer process; for every tonne of alumina produced, approximately 1 to 1.5 tonnes of red mud are also produced. Annual production of alumina in 2020 was over 133 million tonnes resulting in the generatio…Bauxite residue issues: I.
