    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.

    Phosphate Rock | Mosaic Crop Nutrition

    Phosphate rock comes from geologic deposits located around the world. Its main constituent is apatite, a calcium phosphate mineral primarily extracted from sedimentary marine deposits, with a small amount obtained from igneous sources. Most phosphate rock is recovered through surface mining, although some is extracted from underground mines.
