  • 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. The low-grade ore is beneficiated by reverse/inverse flotation

    Phosphate Rock is also often used in landscape and nursery applications to help plants adjust to the stress associated with transplanting. Phosphate Rock cannot burn roots like acidulated phosphate can, and liberal amounts can be applied directly to bare root stock. Phosphates trigger root branching which gives the plant greater access to more of the nutrients it needs.

  • Phosphate Rock Plants: New Source Performance

    Standards of performance for phosphate rock plants were proposed in the Federal Register on September 21, 1979 (44 FR 54970). These standards implement the Clean Air Act and are based on the Administrator's determination that emissions from phosphate rock plants contribute significantly to air pollution which may reasonably be anticipated to endanger public health or welfare.

  • 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 varies greatly, from 4% to 20% phosphorus pentoxide. Marketed phosphate rock is enriched 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 sedimentary rocks is less than 0.2%. The phosphate
