Abstract: India accounts for more than 20 % of the granite deposits of the world. Rock dust or granite slurry is a granite manufacturing waste product resulting due to the cutting and polishing process. Large quantities of rock dust are produced annually. Disposal of this rock dust has become a major problem. Granites are enriched in several alkali and alkaline earth elements such as potassium, aluminium, calcium and several trace elements. The authors have tried to find out the suitability of rock dust to its use as a fertiliser. The granite slurry is having good percentage of potassium and nitrogen with alkaline pH values which can be considered good for fertilizer use rather than keeping it as waste.
