How Can You Separate Alumina From Silica In Bauxite Ore

To separate alumina from silica in bauxite ore associated with silica, first the powdered ore is digested with a concentrated NaOH solution at 473 - 523 K and 35 - 36 bar pressure. This results in the leaching out of alumina Al 2 O 3 as sodium aluminate and silica SiO 2 as sodium silicate leaving the impurities behind.

Bauxite Extraction From Silica Sand

Development of such high-silica ores would be beneficial to alumina producers. Therefore, unique industrial and operational experience in the field of high-silica bauxite processing was gained at the Russian National Aluminium-Magnesium Institute, St. Petersburg, pilot plant with the consecutive extraction of silica and alumina from low-grade ores.

Beneficiation Of High Silica Bauxite Ores Of India An

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.
