Abstract
Alunorte uses dry stacking based on the technology of Giulini for bauxite residue storage. The residue is washed and filtered in drum filters. This paper presents a study of a new technology to move from dry stacking to dry disposal for the next implementation phase of Alunorte’s residue disposal area (DRS). A key element is the use of press filters for residue filtration. With this technology will be possible to increase the residue solids content to about 80 wt.-%. This will result in various advantages, such as maximizing the residue storage capacity as a consequence of steeper disposal angles, increasing lifetime of the DRS, lower amount of water within the dump and lower environmental impact.
