Zusammenfassung:	TREATMENT OF BAYER PROCESS WASTES Red mud filter cake from the Bayer process is mixed with particulate water-swellable water-insoluble polymer such that it can be pumped as a liquid and then rigidifies when placed on a mud stack. The polymer is applied as agglomerates of fine particles or as dispersions in water-immiscible solvent. The polymer is usually an anionic synthetic polymer, for instance formed from acrylic monomers and cross-linking monomer.
