Phosphate rock used for fertilizer is a major NORM due to both uranium and thorium. Phosphate is a common chemical constituent of fertilizer. It is principally mined from apatite and phosphate rocks (phosphorite) in which the concentration of phosphate has been enhanced by sedimentary, igneous, weathering, and biological processes.

Phosphates solubilizing bacterial strains belong to Pantoea, Burkholderia and Enterobacter were isolated and employed in assessing their solubilization ability of Ca phosphate and ER phosphate (Eppawala Rock Phosphate). Among the bacterial strains
Phosphate availability from rock phosphate can be increased over years of cultivation due to the action of soil microbiota (Coutinho et al., 1991 and Silva et al., 2017). Soil microbes also produce organic acids, which is involved in P solubilisation (Mendes et al., 2014…
Phosphate fertilization is a common practice in agriculture worldwide, and several commercial products are widely used. Triple superphosphate (TSP) is an excellent soluble phosphorus (P) source. However, its high cost of production makes the long-term use of crude rock phosphate (RP) a more attractive alternative in developing countries, albeit its influence on plant-associated microbiota ...
The radioactivity of phosphate rock was probably first observed in 1908, when the British physicist R. Strutt found that samples of phosphorite were many times more radioactive than the average rocks of the Earth's crust. 23 The dominant radioactivity detected in phosphate rocks are uranium, thorium and their decay products in equilibrium with ...

Phosphate rock is also the source of by-product fluorine. Apatite & rock phosphate containing 3 to 4% CaF 2 are useful for recovery of fluorite. Hydrofluoro-silicic acid is recovered as by-product from phosphoric acid plants during processing of rock phosphate. Phosphate rocks are also considered as a significant and secondary resource of uranium.

rock phosphate can become soluble (and available to plants) either by chemical weathering or through the actions of certain types of plants. The solubility also depends on rock type and the pH of the soil; phosphorus is most soluble when contained in sedimentary rocks as opposed to igneous rock, and when soil pH is between 5.5 and 7.2.

(gypsum) remains with the product. The rock phosphate required for production of phosphoric acid in the country is mainly obtained through imports. The chemical composition of the Indian rock phosphate as well as imported phosphate rock and production of rock phosphate in India are given in Table 1, 2 and 3 respectively.
Phosphate rock (PR) is a finite mineral indispensable for fertilizer production, while P (phosphorus) is a major pollutant if applied or discharged in excess, causing widespread eutrophication (Carpenter and Bennet, 2011). High-grade PR is obtained from deposits which took millions of years to form and which are gradually being depleted.
