Red mud (bauxite residue) – an unnecessary problem? - #SINTEFblog

Jan 01, 2019 · Let’s answer the first question first. Bauxite residue is a waste product produced by the aluminium industry. To answer the second question – more than twice as much bauxite residue as aluminium metal is produced during a standard production and refinement process. In a linear economy, valuable raw materials are simply dumped

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 oxide compounds, 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 gen
