A process for the removal of reactive silica Process for removing reactive silica certainly in excess of 80% removal of reactive silica from the bauxite

Bayer process

This treatment also dissolves silica but the other components of bauxite do For bauxites having more than 10% silica the Bayer process becomes uneconomic due
