Red mud waste residue management has been a continuing issue for review within the alumina refinery operations. With anywhere from 1 to 2.5 tonnes of red mud residue per tonne of Al 2 O 3 produced, the alumina producer must carefully consider the various options available to handle this material. The most common practice 75 years ago was to dump residue slurry directly to …
