Phosphate Rock - an overview | ScienceDirect Topics

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.

Phosphorite - Wikipedia

Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals. The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5). Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O 5.

Phosphate-rock solubility tests. The solubility tests of PRs using chemical extraction methods are empirical. They offer a simple and rapid method for classifying and then selecting PRs according to their potential effectiveness. They cannot be used to evaluate the amount of plant-available P because the actual agronomic effectiveness of the PR in the field depends on a range of factors. Most ...

Phosphate Rock Properties

18/02/2021· Complete decomposition of the rock and extraction of P2O5 is effected by a countercurrent system. The resultant phosphoric acid is separated from precipitated gypsum and other insoluble constituents by washing the slurry on vacuum filters. The phosphoric acid from the first filter (30 to 32 percent H3PO4) is termed “production acid.” This acid is concentrated by evaporation to 70 to 75 ...
