Prebeneficiation of Low Grade Diasporic Bauxite Ore by waset. AbstractA bauxite ore can be utilized in Bayer Process, if the mass ratio of Al2O3 to SiO2 is greater than 10. Otherwise, its FexOy and SiO2 content should be
Bauxite reacts with NaOH (caustic soda) to form sodium alu minate (Na 2 Al 2 O 4 ) while the silica reacts to form a complex compound of Na 2 O∙Al 2 O 3 ∙SiO 2 . Since the silica content of the bauxite used in the study was relatively low, the formation of this compound is negligible.
silica removal from bauxite by screening how to reduce silica in bauxite Silica Screening Machine For Bauxite Aluminium Factories. ... silica removal from bauxite by screeninghow to reduce the silica content from manganese ore removal of ...
• The bauxite grade is decreasing with the increasing of chinese alumina capacity. • High grade bauxite were excessively used to refine alumina in last years. • The surveyed bauxite resource is about billion tonnes in China, more than 60% of which is medium and low grade bauxite (A/S=4~6).
So the bauxite flotation to desilicication of lowgrade bauxite will have a very important significance for China's aluminum industry. This paper reports an innovative development: the separation of silicon from bauxite with two stages by the stage grinding and stage flotation via the direct flotation, and obtained the high quality bauxite concentrate, the flotation index is favorable.
