  • Rock Phospate vs. Superphosphate - Houzz - Home Design

    Rock phosphate and colloidal phosphate are both pulverized forms of the mineral apatite, generally by-products of a mining process, and slow-release forms of phosphorous. "Colloidal" simply refers to the particle size. Superphosphate is apatite that has been reacted with an acid, thereby changing the chemistry and concentrating the phosphorous.

  • AP-42, CH 8.9: Phosphoric Acid

    Phosphate rock contains 3.5 to 4.0 percent fluorine. In general, part of the fluorine from the rock is precipitated out with the gypsum, another part is leached out with the phosphoric acid product, and the remaining portion is vaporized in the reactor or evaporator.

  • Phosphate fertilizers – Manufacturing process of Phosphate

    Phosphate rock (PR) is the raw material used in the manufacture of most commercial phosphate fertilizers on the market. With access to large, high-quality reserves of phosphate rock, Morocco, China and US are the most important players in phosphate industry.


    dissolution of rock phosphate can maintain recommended levels of P over time (Khasawneh et al., 1980, Bolan et al., 1990, Chien et al., 1990, al and Datta 1991, Chien and Menon 1995). Comparisons of rock phosphate with soluble phosphorus fertilizers are based on a standard formula to express the effectiveness of using rock phosphate (RP) under

  • Phosphate Rock - an overview ScienceDirect Topics

    Phosphate rock used for fertilizer is a major NORM due to both uranium and thorium. Phosphate is a common chemical constituent of fertilizer. It is principally mined from apatite and phosphate rocks (phosphorite) in which the concentration of phosphate has been enhanced by sedimentary, igneous, weathering, and biological processes.

  • Processing Phosphates for Use in the Fertilizer Industry

    Phosphorus is derived from phosphate rock, deposits of which are mined all over the world. And while ground phosphate rock can be applied directly to soil, it is most beneficial to first process the phosphate rock into a form that allows the phosphorus to be more readily absorbed by plants.

  • What Is Rock Phosphate and How to Use It in Your Garden

    Apr 06, 2020· Rock phosphate has long been one of the most widely used soluble organic fertilizers known for promoting healthy growth and development of plants. Ever since it was first discovered in central Florida, in the 1880s, it has been widely used in the United States – the country is the world’s leading producer and consumer of phosphate rock.
