High content of silica results in high soda consumption, which limits the use of high-silica bauxite in the production of Bayer alumina. In this work,the main flotation parameters of high silica bauxite (A/S 5.0) including particle size, pulp pH, collector dosage and dispersant dosage were studied. With an optimal condition of 33% solid density, particle size of -74 μm above 93%, sodium ...

2009-08-01  The high silica bauxite is digested under conditions of low temperature (80–105 °C i.e. atmospheric digestion) and solid–liquid separated under conditions to maximise the amount of undigested reactive silica in the residue. The liquor from the atmospheric digestion is then used to digest further low silica bauxite in a conventional digestion. The second digestion therefore increases the ...

Bauxite is the main raw material in primary aluminum production and its reactive silica content and mass ratio of Al 2 O 3 to SiO 2 (A/S) has a critical role in the economic viability of Bayer process. As a major source of the reactive silica, clay impurities should be removed from the ore as much as possible by a beneficiation method such as froth flotation before the Bayer processing.
