Investigation of Flotation Behaviors of Refractory High ...

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.

Bauxite Beneficiation Flotation Silica Iron. In addition, the higher the kaolinite or reactive silica content of the bauxite, the more red mud will be generated. The reactive silica content not only increases the volume of red mud, but also consumes caustic soda reagent and reduces the yield of Al2O3 recovered from the bauxite.

However, a high-grade bauxite contains up to 60% Al2O3, and many operating bauxite deposits are well below this, occasionally as low as 30-40% Al2O3. Because the desired product is a high purity Al2O3, the remaining oxides in the bauxite (Fe2O3, SiO2, TiO2, Organic material) are separated from the Al2O3 and rejected as alumina refinery resides (ARR) or red mud.

Abstract. Many bauxite reserves in India have Al 2 O 3 /SiO 2 ratio of 4 to 6 and hence pose difficulties in production of alumina through the Bayer process. The extraction of alumina from bauxite in low temperature digestion circuit frequently involves a desilication step in which kaolinite dissolves and reprecipitates as sodalite, a caustic insoluble sodium alumino silicate.

(PDF) Extracting Silica and Alumina from Low-Grade

Alkali leaching of silica from activation-roasted high-silica bauxite can increase the mass ratio of alumina to silica (A/S) in the residue and favors alumina extraction by the Bayer process.

Implementation of reverse flotation method to reduce ...

This paper reports a study that implements reverse flotation method to separate silica from West Kalimantan bauxite ores. The study is aimed to find the good process condition to obtain low-silica bauxite as the feed for the Bayer process. The experiments were carried out in a 1 L of flotation cell tank. Dodecylamine was used as the collector, starch as the depressant, and MIBC as the frother.

The first fraction corresponded to crystallized bauxite (CB), commercially exploited by industry, whereas the other one corresponded to crystallized amorphous bauxite (CAB) - a marginal bauxite unprofitable to the Bayer process due to its high contents of reactive silica, with particle size lower than 100 mm. Samples were submitted to a study on the influence of the addition of an alkaline ...

The results of XRF of products show that in all reverse flotation experiments, the ratio of alumina to silica (Al/Si) are increased from 7 up to 14. The increase of solid percentage in the flotation gives a good result for Al/Si ratio as well as alumina and silica recovery in concentrate, with 30% w/w solid percentage to solution increases Al/Si ratio to 14.38, with silica recovery of 20%.
