• 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 an overview ScienceDirect Topics

    Rock phosphate, the primary raw material for fertilizer and phosphoric acid, occurs as high-grade ore (+30% P 2 O 5), medium-grade ore (20%–30% P 2 O 5), and low-grade ore (15%–20% P 2 O 5). The very high-grade ore blends with medium-grade ore for direct sale. The high-grade ore is mined, crushed, and sold to various fertilizer plants.
