Red mud - Wikipedia

Red mud, formally termed 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 ...
