Disclosed herein are silicon containing polymers and compositions containing the same able to flocculate suspended solids in the Bayer or Sinter process stream.

Silicon containing polymer flocculants

Disclosed herein are methods of producing alumina trihydrate crystals from an alumina trihydrate recovery process stream wherein an aqueous emulsion comprising a crystal growth modifier, which is at least one of an acyclic anhydride or an alkyl or alkenyl succinic anhydride, is added to the alumina trihydrate recovery process stream, wherein the aqueous emulsion is substantially free of mineral oils. The method provides a decrease in percentage of alumina trihydrate crystals having a volume average diameter of less than about 45 micrometers compared to the percentage of alumina trihydrate crystals produced in the absence of the crystal growth modifier. The process does not require the addition of a defoamer/anti-foam agent in order to control foam generated in the process.

Oil free crystal growth modifiers for the bayer process

Methods for reducing aluminosilicate containing scale in an alumina recovery process involving treating an alumina recovery process equipment surface with a degradation-resistant scale inhibiting composition having high ionic strength prior to exposure to an alumina recovery process stream.

Degradation-resistant scale inhibitors

Methods for reducing aluminosilicate containing scale in a Bayer process involving treating a Bayer process equipment surface with a scale inhibiting composition having high ionic strength prior to exposure to a Bayer process stream.
