  • Phosphorite Wikipedia

    Phosphorite, phosphate rock or rock phosphate is a nondetrital sedimentary rock that contains high amounts of phosphate mineralsThe 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
