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% [1] to 20% phosphorus pentoxide (P 2 O 5 )Rock phosphate | Feedipedia,Rock phosphates from some areas (eg, Curacao) are low in fluorine, whereas those from other areas must be defluorinated before they can be used Defluorination of rock phosphate is an industrial process that is suitable only for large-scale production Rock phosphate contains about
