USE OF SILICON-CONTAINING POLYMERS TO IMPROVE RED MUD FLOCCULATION IN THE BAYER PROCESS

The suspended solids content of a Bayer process stream is reduced by contacting the stream with silicon-containing polymers. La teneur en matières solides en suspension dun courant de procédé de Bayer est réduite en mettant en contact le courant avec des polymères contenant du silicium.
