SELECTION OF SEDIMENTATION EQUIPMENT FOR THE BAYER PROCESSrnAN OVERVIEW OF PAST AND PRESENT TECHNOLOGY

摘要

The Bayer Process relies heavily on sedimentation Equipment inrnDesilication, Liquor Clarification, Residue Disposal, TertiaryrnSeed Classification, as well as Caustization andrnOxalate Removal.rnOver the past 20 years, sedimentation equipment design andrnoperating philosophies have changed dramatically with the adventrnof feed slurry dilution, new flocculants, and robotic descaling.rnThis paper will present and overview of the progression of BayerrnProcess sedimentation technology and current equipment optionsrnavailable.
