Processing bauxite
Webb14 apr. 2024 · Bauxite residue or red mud is a waste generated from the processing of bauxite into alumina through the Bayer process [ 1 ]. The quantity of red mud produced for every ton of alumina production is significant, and thus the storage of red mud is a challenge for alumina producers. Webb15 feb. 2024 · Using a new combination of disruptive technologies, the planned bauxite residue processing plant will initially have the capacity to process 50,000 tonnes of bauxite residue per year. The new technology has proved successful in laboratory scale tests and will turn bauxite residue into a resource.
