KERA PROCESS OF SSP MAKING FROM INDIAN ROCK PHOSPHATES

摘要

An invention to provide viable technology of Thermal Treatment to any Grade of Indian Rock Phosphates/Apatite which may or may not be amenable to enrichment. Process involves using Silicic Anhydride in total replacement of Sulfuric Acid to transform Apatite/Rock Phosphates to Single Super Phosphate [SSP] richer in water soluble Phosphorus [P2O5] being absolutely free from inert Gypsum dilution and with soil friendly Mono-calcium Silicate to the contrary.
