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.

Feb 18, 2021 · Defluorinated and Fused Phosphate Rock. Defluorinated phosphates are obtained by calcining or fusing phosphate rock with silica and/or phosphoric acid in the presence of water vapor. At temperatures ranging from 1,400° to 1,600° C., the bulk of the fluorine is evolved, and the P2O5 is rendered citrate soluble.

Ground phosphate rock is reacted with sulfuric acid to form a semisolid, which cools for several hours in a den. The plasticlike material is then conveyed to a storage pile for several weeks of additional curing. The hardened material is then milled and screened to the appropriate particle size or granulated.

A Homeowner's Guide to Fertilizer: Understanding the Fertilizer Label : All fertilizer labels have three bold numbers. The first number is the amount of nitrogen (N), the second number is the amount of phosphate (P 2 O 5) and the third number is the amount of potash (K 2 O). These three numbers represent the primary nutrients (nitrogen(N) phosphorus(P) potassium(K)).
