The filtration rate of Bayer Process primary settler feed and/or the flocculation in the initial stages of the washer train in the Bayer Process are improved by contacting the settler feed stream or the feed stream to the first stages of the washer train first with a) a lower molecular weight polymer which contains hydroxamic acid and/or salt groups and then with b) a mixture of an anionic polymer and a second, higher molecular weight polymer which contains hydroxamic acid groups.

La vitesse de filtration de la charge primaire de décantation utilisée dans le cadre du procédé Bayer et/ou la floculation dans les phases initiales du circuit de lavage réalisé dans le cadre du procédé Bayer sont améliorées en soumettant le flux de charge de décantation ou le flux de charge des étapes initiales du cycle de lavage au contact a) d'un polymère à poids moléculaire plus faible contenant de l'acide hydroxamique et/ou des groupes de sels hydroxamiques puis b) à un mélange constitué par un polymère anionique et par un deuxième polymère, à poids moléculaire plus élevé, qui contient des groupes acides hydroxamiques.
