Phosphorite - Wikipedia

Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock which 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

Phosphate rock margins squeezed as tighter EU

11/10/2017  Rock blending and calcination are two processes implemented within rock beneficiation which help to reduce cadmium levels. However, the adaption and viability of these process is limited. Beyond rock beneficiation, between 10-30% of cadmium is removed via the phosphoric acid process. The cost curves presented below are a collation of sites with collected cadmium deposit data,

How phosphate is mined and processed

rock phosphate can become soluble (and availe 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.
