    The source of fluorides is phosphate rock, which contains from 3.5% to 4.0% (w/w) fluorine. The fluorine is generally precipitated out with gypsum, leached out with phosphoric acid product, or vaporized in the reactor or evaporator. The reactor where phosphate rock is contacted with sulfuric acid is the primary source of emissions.

  • How phosphate is mined and processed

    rock phosphate can become soluble (and available to plants) either by chemical weathering or through the actions of certain types of plants. The solubility also depends on rock type and the pH of the soil; phosphorus is most soluble when contained in sedimentary rocks as opposed to igneous rock, and when soil pH is between 5.5 and 7.2.
