Silica extraction from bauxite reaction residue and

First, the silicate mineral reacts chemically with the alkali during the reaction, and then the silica enters the solution in the form of SiO 3 2−. The silicate ion reacts with sodium aluminate and calcium hydroxide respectively, and then silicon precipitates out in the form of hydrated sodium aluminosilicate and hydrated calcium silicate . These precipitates cover the surface of the ALBRR and further hinder the extraction
