  • 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.
