    OverviewGeologyUseGeographyHistoryEnvironmental impactsByproductsInternational trade

    Although some igneous rocks have economic grades of phosphate, no igneous phosphate rock is mined in the US. Small amounts of phosphate were mined from igneous apatite deposits in Virginia, New Jersey, and New York. But since 1948, all phosphate deposits mined in the US have been sedimentary deposits. However, a small amount of phosphate was produced in the 1970s, as a byproduct of iron mining in Missouri.

  • The Mining Process Mining The Phosphate Risk

    In Florida, the phosphate rock is extracted by a process referred to as strip-mining. Unlike mining in other states, phosphate deposits are found closer to the surface, about 30-40 feet below ground. Sandy topsoil, also known as overburden, is removed by large digging machines called draglines.
