  • 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.
