A novel process for the manufacture of precipitated silica from rice husk ash, having a surface area ranging from$50-400m^2/g$ and tap density of $80-600kg/m^3$ having multiple applications in the field of rubbers and plastics, paints, toothpastes, catalyst, carrier agent, insulation, stabilizing and desiccants. The process method for silica precipitation is novel, where in the chemicals used are regenerated making it a closed loop operation. The extraction process through digestion, precipitation and regeneration are done based on the application specifies, so as to get the required particle size and densities.
