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.

How phosphate is mined and processed

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.
