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 extraction of silica and alumina from lowgrade ores.
Estimation of ore washing potential and the selection of cut size is essential for the establishment of a bauxite washing plant. In the current research study, a simple ultrasonic washing technique has been developed for the removal of clay and to determine the potential of an industrial washing process at various cut sizes.
