Tiles From Granite Slurry (New upcoming technology)

India has got best granite deposits in the world. It accounts for over 20% of total Granite reserve of the world. Total Granite reserve is in India is about 42,916 million cubic meters. Granite slurry is the waste generated during cutting and polishing of stone.

Physical and Chemical Properties of Granite Slurry:
