    Swapan Kumar Haldar, in Mineral Exploration (Second Edition), 2018. 13.5.7.5 Flotation of Rock Phosphate Ore. 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.

    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(P2O5). Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P2O5. This occurs through washing, screening, de-liming, magnetic separation or flotation. By comparison, the average phosphorus content of sedimentar

    rock phosphate can become soluble (and available to plants) either by chemical weathering or through the actions of certain types of plants.
