METHOD OF TREATING BEYER PROCESS STREAMS Russian patent published in 2004 - IPC

Abstract RU 2239600 C2

FIELD: industrial inorganic synthesis.

SUBSTANCE: invention improves Beyer alumina production process via introducing removal of colloidal iron and/or other impurities from process streams my making them interact with amidoxime-based polymer. Process stream comes into contact with polymer at stirring and thus formed polymer-iron complex is then separated to leave cleaned sodium aluminate solution.

EFFECT: reduced colloidal iron level in Beyer process stream.
