Title:

Processes for the Utilization of Kimberlite Waste for the Manufacture of Sodium Silicate, Detergent Grade Zeolite A and Precipitated Silica
Value Proposition:

Processess for the preparation of sodium silicate, detergent grade zeolite A and precipitated silica.
Summary Application:

A process for the utilization of kimberlite waste for the preparation of sodium silicate on ~ 50 kg/batch has been developed. Processes for the preparation of detergent grade zeolite-A (10 kg/batch) and precipitated silica (5 kg/batch) have been developed using the sodium silicate prepared from Kimberlite waste.
Advantages:
  • Conversion of the waste to value added products make diamond mining more environmental friendly.
  • There is a scope of preparation of magnesia and titania base products
  • Environmentally friendly technology
Commercialization Status: Already Commercialised
