Abstract. Deposits of bauxite ores near aluminum smelters often possess an excessively high percentage of silica. Development of such highsilica ores would be beneficial to alumina producers. Therefore, unique industrial and operational experience in the field of highsilica bauxite processing was gained at the Russian National AluminiumMagnesium Institute, St. Petersburg, pilot plant with the consecutive
Processing Of High Silica Bauxite. Mining and Refining Process. The bauxite is washed and crushed, reducing the particle size and increasing the availe surface area for the digestion stage. Lime and quot;spent liquorquot; (caustic soda returned from the precipitation stage) are added at the mills to make a pumpable slurry. 2. Desilication.
A process for removing silica from bauxite is disclosed. The method includes the step of mixing bauxite with a caustic liquor to form a mixture and to dissolve and stabilise at least a substantial...
